(2S)-2-hydroxypropanoic acid

(2S)-2-hydroxypropanoic acid is the S-enantiomer of lactic acid, a naturally occurring organic acid with the molecular formula C3H6O3. This chiral compound has a molecular weight of 90.08 g/mol and is classified as a corrosive substance under GHS regulations. It is characterized by the presence of both a carboxyl group and a hydroxyl group, making it an alpha-hydroxy acid with significant industrial and biological importance.

(2S)-2-hydroxypropanoic acid is typically a colorless to slightly yellow liquid or crystalline solid at room temperature. It is highly soluble in water and polar solvents due to its hydroxyl and carboxyl functional groups. The compound has a slightly sour odor characteristic of organic acids. Its corrosive nature (Skin Corr. 1C; Eye Dam. 1) indicates it can cause severe chemical burns upon contact with skin and eyes.

(2S)-2-hydroxypropanoic acid is widely used in the food industry as an acidulant, preservative, and flavoring agent. It serves as a key intermediate in pharmaceutical manufacturing and is utilized in the production of biodegradable polymers like polylactic acid (PLA). The compound also finds applications in cosmetics as an exfoliating agent, in leather tanning processes, and as a pH regulator in various industrial formulations.

(2S)-2-hydroxypropanoic acid requires careful handling due to its corrosive properties. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, and protective clothing to prevent skin and eye contact. Work should be conducted in well-ventilated areas or under fume extraction systems. Emergency eyewash stations and safety showers must be readily accessible. Avoid generating aerosols and ensure proper training on corrosive substance handling procedures before use.

(2S)-2-hydroxypropanoic acid should be stored in tightly sealed, corrosion-resistant containers made of suitable materials like high-density polyethylene or glass. Storage areas must be cool, dry, and well-ventilated, away from incompatible materials such as strong bases, oxidizing agents, and metals. Containers should be clearly labeled and stored in secondary containment to prevent spills. Regular inspection of storage containers is essential to detect any signs of corrosion or leakage.

Immediate action is required upon contact with (2S)-2-hydroxypropanoic acid. For skin contact, remove contaminated clothing and flush the affected area with copious amounts of water for at least 15 minutes. In case of eye contact, rinse immediately with water for at least 15 minutes while holding eyelids open. If inhaled, move the person to fresh air. Seek immediate medical attention in all cases of exposure, as this substance can cause severe chemical burns.

(2S)-2-hydroxypropanoic acid waste must be disposed of according to local and national hazardous waste regulations. The substance cannot be disposed of in regular drains or waste streams due to its corrosive classification. Waste should be collected in appropriate containers and handed over to licensed waste disposal companies. Neutralization may be possible under controlled conditions by qualified personnel, but professional waste management services are recommended for safe and compliant disposal.

(2S)-2-hydroxypropanoic acid is classified as ADR Class 8 (corrosive substances), Packing Group III for transportation purposes. This classification requires specific packaging, labeling, and documentation for shipment. Packages must bear appropriate hazard labels and be constructed to withstand the corrosive nature of the contents. Transport vehicles must comply with ADR regulations, and drivers require proper training and certification for carrying corrosive materials.

(2S)-2-hydroxypropanoic acid is regulated under the CLP Regulation in Europe, requiring appropriate classification, labeling, and safety data sheets. While it is not currently listed as a Substance of Very High Concern (SVHC) under REACH, suppliers must comply with registration requirements if importing or manufacturing above specified tonnage thresholds. Food-grade applications are subject to additional food safety regulations, and pharmaceutical uses require compliance with relevant medicinal product legislation.
