Sodium 2-methylpropanoate(CAS: 996-30-5)

Sodium 2-methylpropanoate appears as a white crystalline solid. Its molecular weight is approximately 126.13 g/mol. It is highly soluble in water and ethanol. Chemically, it is moderately reactive, particularly with bases and acids. It is less reactive than its carboxylic acid counterpart, 2-methylpropanoic acid.

Sodium 2-methylpropanoate is typically synthesized by the reaction of 2-methylpropanoyl chloride with sodium hydroxide. This process involves the deprotonation of the carboxylic acid chloride to form the sodium salt. The reaction is exothermic and requires careful temperature control to prevent side reactions.

Sodium 2-methylpropanoate is used in various industries, including pharmaceuticals, where it serves as a precursor in the synthesis of certain drugs. It is also utilized in the production of polymers and in organic synthesis for the preparation of other chemicals. Its use in sensors and semiconductors is less common but still relevant due to its reactivity and solubility properties.

When handling Sodium 2-methylpropanoate, it is important to wear appropriate personal protective equipment (PPE) including gloves, goggles, and a lab coat. It should be stored in a cool, dry place away from incompatible substances like acids and bases. Spills should be handled carefully, using appropriate absorbents, and the area should be well-ventilated to avoid inhalation risk. Always refer to the Safety Data Sheet (SDS) for detailed handling and storage instructions.
