Overview
Mesolactic acid is a stereoisomer of lactic acid, characterized by its unique meso form, which makes it optically inactive. It is widely used in various industries due to its mild acidity and stability. Unlike other lactic acid isomers, mesolactic acid does not rotate plane-polarized light, making it valuable in applications requiring consistent chemical behavior. This compound is synthesized through chemical processes that ensure high stereochemical purity. Its versatility and safety profile make it a preferred choice in food preservation, pharmaceuticals, and biodegradable polymers. The demand for mesolactic acid is growing, particularly in eco-friendly and sustainable applications.
Physical and Chemical Properties
Mesolactic acid is a colorless to pale yellow liquid with a mild acidic odor. It has a density of 1.206 g/cm³ at 25°C and a melting point of 16.8°C. The boiling point is 122°C at 15 mmHg, indicating its relatively low volatility under standard conditions. The compound is highly soluble in water, ethanol, and ether, making it easy to incorporate into various formulations. Its key chemical properties include mild acidity (pKa ~3.86) and high stability under normal storage conditions. These properties make it suitable for applications where consistent performance is critical.
Main Applications
Mesolactic acid is extensively used in the food industry as a preservative and acidity regulator. It is also a key intermediate in pharmaceutical synthesis, particularly in the production of biodegradable polymers and drug formulations. Its mild acidity and stability make it ideal for cosmetic and personal care products. In the chemical industry, mesolactic acid serves as a building block for synthesizing other compounds, such as lactates and esters. Its eco-friendly profile has led to increased use in sustainable and green chemistry applications. The compound’s versatility ensures its relevance across multiple sectors.
Safety and Storage
Mesolactic acid is generally safe when handled properly, but it can cause irritation upon contact with skin or eyes. It is advisable to use personal protective equipment, such as gloves and goggles, when working with this chemical. Ensure adequate ventilation in workspaces to avoid inhalation of vapors. Storage should be in a cool, dry place away from direct sunlight and incompatible materials, such as strong oxidizers. Proper labeling and secure containers are essential to prevent accidental exposure or spills. Always follow local regulations for chemical storage and disposal.
B2B Procurement Guide
When procuring mesolactic acid, verify the CAS number (598-82-3) and purity specifications to ensure product quality. Reputable suppliers should provide certificates of analysis (CoA) and material safety data sheets (MSDS). Bulk purchases often come with cost advantages, but ensure storage capacity aligns with usage rates. Consider the intended application when selecting purity grades. For food and pharmaceutical uses, opt for higher purity grades (≥98%). Price ranges vary based on volume and supplier, with typical costs between $5-$10 per kg. Establish long-term relationships with suppliers to secure consistent quality and favorable terms.
