Potassium Perchlorate CAS 7778-74-7

What Is Potassium Perchlorate?

Potassium perchlorate is an inorganic potassium salt of perchloric acid with the chemical formula KClO4 and CAS No. 7778-74-7. It is normally supplied as a white crystalline powder and is classified as a strong oxidizing solid.

The substance is not itself a fuel, but it can greatly accelerate the combustion of combustible materials. For this reason, purchasing, packaging, storage, handling, transport and end use require stricter controls than ordinary inorganic salts.

AOZUN supplies potassium perchlorate to qualified industrial and laboratory buyers, subject to product availability, destination regulations, end-use review and dangerous-goods transport arrangements.

Is Potassium Perchlorate Organic or Inorganic?

Potassium perchlorate is an inorganic compound.

It consists of potassium ions and perchlorate ions and contains no carbon-based organic structure. More specifically, it belongs to the following chemical classes:

• Inorganic salts

• Potassium salts

• Perchlorates

• Oxidizing agents

• Specialty inorganic chemicals

For website classification, the recommended primary category is:

Inorganic Chemicals → Specialty Oxidizers

It may also be listed under “Fine Chemicals” when supplied with tightly controlled assay, impurities and particle-size specifications.

Is Potassium Perchlorate a Fine Chemical or an Intermediate?

Potassium perchlorate is better described as an inorganic fine chemical and specialty oxidizer than as a conventional chemical intermediate.

It may serve as a raw material in regulated industrial formulations or specialized chemical processes, but it is generally consumed for its oxidizing function rather than converted into a broad range of downstream intermediates.

Recommended classification:

• Primary: Inorganic fine chemical

• Functional category: Strong oxidizer

• Chemical family: Perchlorate salt

• Secondary description: Controlled industrial raw material

• Not recommended: Pharmaceutical intermediate

Potassium Perchlorate Identification at a Glance

The physical-property values above are reference information. The current specification, batch COA and supplier SDS should be used for purchasing and handling decisions.

What Grades of Potassium Perchlorate Are Available?

Industrial Grade

Industrial-grade potassium perchlorate is intended for authorized manufacturing and technical processes where assay, moisture, related salts and particle size are controlled.

Important parameters may include:

• Potassium perchlorate assay

• Moisture

• Potassium chloride

• Potassium chlorate

• Bromate

• Sodium perchlorate

• Water-insoluble matter

• Iron

• Calcium and magnesium

• Particle-size distribution

• Batch consistency

Industrial grade should not automatically be treated as analytical, ACS or high-purity grade.

Reagent or Analytical Grade

Reagent grades are intended for laboratory analysis, research and controlled chemical procedures.

These grades may specify:

• Assay by titration

• Insoluble matter

• Chloride

• Sulfate

• Sodium

• Calcium

• Iron

• Heavy metals

• Identity testing

• COA availability

Reagent packages may also be subject to customer verification and regulatory review before shipment.

ACS-Comparable Grade

An ACS specification generally includes a more detailed impurity profile than a basic industrial specification.

A published reagent-grade framework may include:

• Assay around 99.0–100.5%

• Insoluble matter

• Chloride

• Sulfate

• Calcium

• Sodium

• Iron

• Heavy metals

A supplier should not describe a product as ACS grade unless the material is tested against the applicable current requirements.

High-Purity or Trace-Metals Grade

Research, analytical and selected materials applications may require very low trace-metal levels.

In these cases, buyers should define:

• Purity basis

• Total trace-metal limit

• Individual metal limits

• Analytical method

• Detection limits

• Packaging cleanliness

• Batch-specific reporting

A high headline assay does not automatically establish low levels of every critical impurity.

Typical Industrial Specification

The following table reflects AOZUN’s currently published Type II industrial framework. Confirm the latest approved specification before presenting it as a contractual guarantee.

Additional limits for bromate, sodium perchlorate, calcium, magnesium, water-insoluble matter, iron or pH can be agreed when available.

The final purchase specification should identify the analytical method and acceptance criteria for each critical parameter.

Which Quality Parameters Should Buyers Compare?

Potassium perchlorate from different suppliers should not be compared using assay alone. Related oxidizing salts, moisture, insoluble matter, metals and particle-size distribution can affect process control, storage and downstream qualification.

Assay

The specification should state:

• Minimum or accepted assay range

• Test method

• Dry or as-received basis

• Rounding rules

• Whether results appear on every batch COA

A result reported by titration may not be directly comparable with a result obtained using another analytical method.

Chlorate Content

Residual potassium chlorate is a critical related-salt parameter. Buyers should specify the maximum accepted limit and analytical method.

The permitted value depends on the intended industrial process and applicable specification. Potassium chlorate and potassium perchlorate must not be treated as interchangeable materials.

Chloride and Other Related Salts

Potassium chloride, sodium perchlorate, bromate and other ionic impurities may be relevant to process consistency, analytical work and downstream material performance.

A complete specification is more useful than a general statement such as “99% purity.”

Moisture

Moisture can affect powder handling, storage behavior, weighing and processing consistency.

The purchase specification should identify whether moisture is measured by:

• Karl Fischer titration

• Loss on drying

• Another agreed method

Water-Insoluble Matter

Insoluble matter can be important where potassium perchlorate is dissolved, recrystallized or used in analytical procedures.

A reagent-grade specification may include a much lower limit than an ordinary industrial grade.

Trace Metals

Iron, calcium, magnesium, sodium and other metals may matter in analytical and high-purity applications.

Buyers should define:

• Individual impurity limits

• Total metal limit

• ICP-OES, ICP-MS or other test method

• Required detection limits

Particle-Size Distribution

Particle size affects powder flow, dust generation, blending uniformity and process consistency.

For safe procurement, particle-size requirements should be expressed as a controlled sieve or distribution specification without assuming that one particle size is suitable for every application.

The buyer and supplier should agree on:

• Test method

• Sieve sizes

• Minimum pass rate

• Oversize limit

• Fine-particle limit

• Sampling procedure

Material should not be ground, milled or otherwise modified by unqualified personnel. Mechanical processing of strong oxidizers requires a professionally designed and authorized safety system.

Batch-to-Batch Consistency

For repeat purchasing, recent COAs should be reviewed for variation in:

• Assay

• Moisture

• Chlorate

• Chloride

• Particle size

• Insoluble matter

• Critical metals

A consistent product close to the center of the agreed specification may be more useful than a single unusually high assay result.

How Is Potassium Perchlorate Used?
