Ethyl Pyruvate CAS 617-35-6

What Is Ethyl Pyruvate?

Ethyl Pyruvate is the ethyl ester of pyruvic acid and an organic α-keto ester used primarily as a fine-chemical synthesis intermediate.

Its molecule contains both a reactive ketone group and an ester group, making it suitable for multiple transformation routes in pharmaceutical, agrochemical, fragrance and specialty-chemical synthesis.

Ethyl Pyruvate is generally supplied as a clear colorless to pale-yellow liquid. Commercial grades differ in assay, water content, acidity, related impurities and regulatory documentation.

Ethyl Pyruvate Product Information

Physical-property values are reference ranges. The contractual specification and COA should be used for acceptance.

Is Ethyl Pyruvate Organic or Inorganic?

Ethyl Pyruvate is an organic compound belonging to the α-keto ester family.

It is both a fine chemical and a chemical intermediate. For website organization, it is best placed under Organic Intermediates, with Fine Chemicals as a secondary category.

It is normally used as a building block rather than as a basic commodity solvent.

Why Is Ethyl Pyruvate Used as an Intermediate?

Ethyl Pyruvate combines ketone and ester functionality in one relatively small molecule. This allows it to participate in hydrogenation, amination, condensation and carbon–carbon bond-forming reactions.

Its reactivity makes it useful in the preparation of more complex molecules, including selected amino-acid derivatives, heterocyclic compounds and specialty intermediates.

The required purity and impurity profile depend on the downstream reaction and purification process.

Where Is Ethyl Pyruvate Used?

Pharmaceutical and Fine-Chemical Synthesis

Ethyl Pyruvate can serve as a starting material or intermediate in multi-step organic synthesis. Commercial suitability depends on assay, water, acidity and related impurities.

This use does not mean that the supplied industrial product is a pharmaceutical active ingredient or approved drug product.

Agrochemical Intermediates

Its reactive carbonyl functionality may be used in the manufacture of selected crop-protection intermediates and other specialty molecules.

Flavor and Fragrance Manufacturing

Appropriately documented grades may be evaluated as flavoring substances or fragrance raw materials where permitted.

Food, flavor or “natural” status must be supported by the exact production route, traceability documents and destination-market regulations. An industrial synthesis grade should not automatically be described as food grade.

Research and Reagent Applications

High-purity grades may be used in laboratory synthesis, reaction development and analytical research.

Which Ethyl Pyruvate Specifications Matter?

For synthesis projects, buyers should provide impurity limits rather than requesting only a general “98% grade.”

How Should Ethyl Pyruvate Be Stored?

Ethyl Pyruvate is moisture-sensitive, heat-sensitive and flammable. Some grades are packed under inert gas to improve storage stability.

Store it:

• In tightly closed, compatible containers

• In a cool and well-ventilated area

• Away from heat, sparks and open flames

• Away from strong oxidizing agents

• Protected from moisture and unnecessary light exposure

• Under inert gas when required by the supplier’s specification

The exact storage temperature should follow the grade-specific label and SDS. Do not apply a reagent-grade storage temperature automatically to every commercial grade.

Use grounded equipment, non-sparking tools and appropriate ventilation. Wear suitable gloves and eye protection.

What Documents Should a Supplier Provide?

Depending on the application, buyers may request:

• Certificate of Analysis

• Safety Data Sheet

• Technical Data Sheet

• GC chromatogram

• Water and acidity results

• Residual-solvent statement

• Origin or manufacturing-route statement

• Regulatory declaration

• Natural-origin documentation, when applicable

• Packaging and transport information

A “natural” declaration should never be based only on the product name or odor.

Why Source Ethyl Pyruvate from AOZUN?

AOZUN can support buyers with:

• Grade and assay matching

• Application-specific impurity review

• COA, SDS and technical-document support

• Sample evaluation

• Compatible export packaging

• Logistics coordination for flammable liquids

• Pre-shipment quality verification

Grade availability, natural status and regulatory documentation should be confirmed before purchase.

Ethyl Pyruvate FAQ

Is Ethyl Pyruvate an organic chemical?

Yes. It is an organic α-keto ester containing both ketone and ester functional groups.

Is Ethyl Pyruvate a fine chemical or an intermediate?

It is both. Commercially, it is mainly positioned as a fine organic intermediate for downstream synthesis.

Is every Ethyl Pyruvate grade suitable for food flavoring?

No. Food or flavor use requires a specifically compliant grade and appropriate regulatory, purity and traceability documents.

Why is water content important?

Water may influence moisture-sensitive reactions, storage stability, assay results and downstream purification.

Does Ethyl Pyruvate require refrigerated storage?

Some grades recommend refrigerated or cool storage, while others may have different requirements. Follow the exact product specification, label and SDS.
