Malonic acid
Description
Malonic acid (CAS 141-82-2) is a short-chain dicarboxylic acid used across pharmaceutical synthesis, specialty chemical manufacturing, and personal care formulation. It functions primarily as a reactive intermediate and pH buffering agent.
This versatile compound enables precise control in synthesis and formulation processes. In pharmaceutical manufacturing, it serves as a key building block in the synthesis of barbiturates and vitamin B1 via the malonic ester synthesis route.
Personal care formulators use it as a pH adjuster and mild preservative-boosting agent in skin care products. Controlled acidity supports formulation stability while maintaining the efficacy of active ingredients in various cosmetic applications.
In food applications, it acts as an acidulant and flavoring component, contributing a clean tart note to certain processed food products. The compound also functions as a catalyst precursor and chelating agent in specialty chemical processes.
Malonic acid is supplied as a white crystalline powder in a range of pack sizes from laboratory quantities to bulk industrial volumes. Standard commercial grades include technical grade and pharmaceutical-grade material.
Our high-purity material meets USP and BP specifications for pharmaceutical use. Food-grade material compliant with FCC standards is also available for flavor and food acidulant applications to ensure safety and quality.
