Benzoic acid, calcium salt (2:1)(CAS: 2090-05-3)

Benzoic acid, calcium salt (2:1) is a white, crystalline solid with a molecular weight of approximately 224.24 g/mol. It is sparingly soluble in water but soluble in ethanol. The salt is relatively stable and exhibits weak acidity. It reacts with bases to form benzoate salts and can undergo esterification reactions.

Benzoic acid, calcium salt (2:1) is typically synthesized by reacting benzoic acid with calcium hydroxide in an aqueous medium. The reaction is exothermic and the yield is around 85-90%. The process usually involves stirring and filtration to isolate the salt.

Benzoic acid, calcium salt (2:1) is used in the pharmaceutical industry as a preservative, in the food industry as a preservative and flavor enhancer, and in the polymer industry as a stabilizer. It also finds applications in the production of sensors and as a reagent in analytical chemistry.

When handling Benzoic acid, calcium salt (2:1), appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat should be worn. The substance should be stored in a well-ventilated area and handled in a fume hood. Spills should be cleaned up using absorbent materials and disposed of according to local regulations. Always refer to the Material Safety Data Sheet (MSDS/SDS) for detailed safety information.
