Calcium Lactobionate – Anhydrous and Dihydrate

What Is Calcium Lactobionate?

Calcium Lactobionate is the calcium salt of lactobionic acid, a carbohydrate-derived organic acid. It is generally supplied as a white to cream-colored powder with good water solubility.

Depending on the production and drying process, Calcium Lactobionate may be supplied in anhydrous, hydrated or defined dihydrate form. Buyers should confirm the required form before comparing assay, water content or molecular weight.

Calcium Lactobionate Product Information

The approved specification and lot-specific Certificate of Analysis take precedence over these general reference values.

Why Do Calcium Lactobionate CAS Numbers Differ?

CAS No. 5001-51-4 is commonly associated with Calcium Lactobionate described on an anhydrous basis. CAS No. 110638-68-1 is widely used for the defined dihydrate, including pharmacopoeial and reference-standard products.

The form affects:

• Molecular weight

• Water-content limits

• Assay calculations

• Elemental calcium calculations

• Storage behavior

• Pharmacopoeial identification

Purchase orders should specify the required CAS number, hydrate state and whether assay is calculated on the as-is, dried or anhydrous basis.

What Is Calcium Lactobionate Used For?

Pharmaceutical Formulations

Appropriately qualified Calcium Lactobionate may be used as a calcium-containing ingredient in pharmaceutical formulations. Pharmaceutical suitability requires the correct grade, impurity controls and supporting quality documentation.

Material intended for parenteral processing may require additional controls for endotoxins, microorganisms, elemental impurities and manufacturing conditions.

Nutritional and Dietary-Supplement Products

Food- or supplement-grade Calcium Lactobionate may be used as a mineral ingredient when permitted by the destination market. Regulatory status and elemental-calcium calculations must be confirmed for the finished formulation.

Food and Specialty Formulations

FCC-compliant material may be evaluated for permitted food applications. Research or general industrial grade must not be used in food production without the appropriate specification and regulatory documentation.

Laboratory and Analytical Research

Calcium Lactobionate is also available as a reagent or reference material for analytical method development, calcium analysis and carbohydrate-related research.

Which Calcium Lactobionate Grade Do You Need?

Pharmaceutical or USP Grade

The material should comply with the applicable monograph or approved customer specification. Buyers should verify hydrate form, assay basis, calcium content, related substances and regulatory documents.

FCC or Food Grade

Food applications require FCC or other market-appropriate compliance, along with controls for purity, contaminants, microorganisms and traceability.

Research or Reagent Grade

Research-grade material is suitable for laboratory and analytical applications but is not automatically qualified for pharmaceutical or food production.

A purity result alone does not establish suitability for a regulated application.

Which Quality Attributes Should Buyers Compare?

Water content and hydrate state must be reviewed together because they affect assay calculations and the amount of elemental calcium delivered by a given mass.

The required tests and acceptance limits should be agreed before ordering.

Which Documents Should a Supplier Provide?

Depending on the application, buyers may request:

• Lot-specific Certificate of Analysis

• Safety Data Sheet

• Technical Data Sheet

• Approved product specification

• CAS number and hydrate-state confirmation

• USP, FCC or other compliance statement when applicable

• Elemental-impurity information

• Microbiological or endotoxin results when required

• Country-of-origin information

• Manufacturing and retest dates

• Packaging and storage information

Compliance claims should only be used when supported by verified manufacturer documents.

Packaging, Storage and Handling

Store Calcium Lactobionate in a tightly sealed container in a cool, dry and clean location. Protect it from moisture, contamination and excessive heat.

Because water content is an important specification, opened packaging should be resealed promptly. Packaging size, shelf life and storage conditions should be confirmed with the quotation.

Always consult the current Safety Data Sheet before handling.

Frequently Asked Questions

Is Calcium Lactobionate organic or inorganic?

It is an organic calcium salt derived from lactobionic acid. It should not be classified in the same way as simple inorganic salts such as calcium chloride or calcium carbonate.

Is Calcium Lactobionate a fine chemical or an intermediate?

It is primarily a fine chemical, pharmaceutical ingredient or nutritional ingredient. It is not usually sold as a chemical synthesis intermediate.

Are CAS 5001-51-4 and 110638-68-1 the same product?

Both refer to Calcium Lactobionate, but they are commonly used for different hydration states. CAS 110638-68-1 generally identifies the defined dihydrate. The required CAS and hydrate form should be confirmed before ordering.

What is the difference between Calcium Lactobionate and Calcium Lactate?

They are different calcium salts. Calcium Lactobionate is derived from lactobionic acid, while Calcium Lactate is derived from lactic acid. They have different molecular weights, specifications and formulation properties.

Is Calcium Lactobionate soluble in water?

Yes. Calcium Lactobionate is generally described as freely soluble in water, making it suitable for selected aqueous formulations.

Can research-grade material be used in food or pharmaceutical products?

Not automatically. Food and pharmaceutical applications require the appropriate manufacturing controls, specifications and regulatory documentation.
