Pyruvic acid

Pyruvic acid (CAS 127-17-3), also known by its FEMA 2970 designation, is a short-chain alpha-keto acid used across pharmaceutical synthesis, food flavoring, and cosmetic formulation. It functions as a reactive intermediate, acidulant, and surface-modifying agent depending on the application. In pharmaceutical manufacturing, it serves as a key building block for synthesizing amino acids and vitamins.

This keto-acid scaffold is essential for active pharmaceutical ingredients where metabolic relevance is required. Food and beverage producers use it as a flavoring agent, contributing subtle acidic and fruity notes to products. In cosmetics, it is applied as a chemical exfoliant in peeling formulations. Its reactivity with skin proteins enables controlled surface renewal at lower concentrations than traditional alpha-hydroxy acids.

It also functions as a catalyst precursor and reagent in specialty organic synthesis. This is particularly useful in condensation reactions targeting fine chemical intermediates for industrial use. The material is supplied as a colorless to pale yellow liquid, typically at concentrations of 98% and above. This high purity is ideal for technical and synthesis-grade applications across various sectors.

Food-grade and pharmaceutical-grade material is available to meet purity requirements for regulated end uses. Packaging ranges from small laboratory quantities to bulk drums suited for industrial procurement.
