Description

Sodium (S)-Lactate is the sodium salt of the naturally occurring L-lactic acid enantiomer, a key biochemical intermediate. This high-purity chiral compound is essential for applications requiring specific stereochemistry, offering superior compatibility and efficacy over racemic mixtures. It serves as a critical raw material and pH regulator for manufacturers in the pharmaceutical, cosmetic, and high-value food industries, where product safety and precise biological activity are paramount.

Application

• Pharmaceutical Synthesis: As a chiral building block for active pharmaceutical ingredients (APIs) and in buffer systems for parenteral formulations.
• Cosmetics & Personal Care: A highly effective humectant and moisturizing agent in skin creams, lotions, and serums; also functions as a pH adjuster and mild exfoliant.
• Food & Beverage Additive: Used as an acidity regulator, flavor enhancer, and shelf-life extender in selected food products, often where the specific (S)-enantiomer is required.
• Biochemical Research: A standard and reagent in enzymatic studies, cell culture media, and microbiological fermentation processes.
• Eco-friendly Formulations: Incorporated into "green" cleaning products and industrial descaling agents as a biodegradable chelating agent.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent absorption of atmospheric moisture, which can lead to caking or dilution.
