3-Mercaptopropionic acid (3-MPA), identified by its CAS number 107-96-0, is a chemical compound characterized by its distinct physical and chemical properties that dictate its handling and application. Understanding these attributes is fundamental for chemists and technicians working with this versatile substance. Available from various suppliers, including those in China, sourcing 3-Mercaptopropionic acid requires attention to its specific characteristics.

Physically, 3-Mercaptopropionic acid is typically described as a colorless oil. Its molecular formula, C₃H₆O₂S, and molar mass of approximately 106.14 g/mol provide essential identifiers. Key physical properties include a melting point typically ranging from 17-19°C and a boiling point of around 110-111°C at 15 mmHg. It is also noted to be soluble in water, ether, benzene, and alcohol, indicating its compatibility with a range of common solvents. When considering its purchase, information regarding the price of 3-Mercaptopropionic acid can guide procurement decisions.

Chemically, 3-MPA is defined by its thiol (-SH) and carboxylic acid (-COOH) functionalities. The thiol group is reactive and can be oxidized to form disulfides or participate in nucleophilic reactions. The carboxylic acid group allows for typical acid reactions like esterification and salt formation. These properties are critical for its use in synthesis and as a cross-linking agent. For those looking to buy 3-Mercaptopropionic acid, it’s important to note its potential hazards.

Safety and handling are paramount when working with 3-Mercaptopropionic acid. According to GHS classifications, it is labeled as toxic if swallowed (H301), causes severe skin burns and eye damage (H314), and is harmful if inhaled (H332). It also carries the hazard statement H290, indicating it may be corrosive to metals. Therefore, appropriate personal protective equipment (PPE), including gloves, eye protection, and protective clothing, is essential. Proper ventilation and avoiding inhalation of vapors are also crucial. When handling, it is recommended to keep it in its original packaging and avoid contact with incompatible materials. Reliable 3-Mercaptopropionic acid manufacturers often provide detailed safety data sheets (SDS) that outline these precautions.

For industrial applications and laboratory research, understanding the properties and safety protocols for 3-Mercaptopropionic acid is non-negotiable. Whether you are a seasoned chemist or new to its use, consulting an SDS from a trusted 3-Mercaptopropionic acid supplier is the first step to ensuring safe and effective utilization. The availability of 3-Mercaptopropionic acid from Chinese manufacturers also presents opportunities for cost-effective sourcing, provided quality and safety standards are met.
