Butyl salicylate(CAS: 2052-14-4)

Butyl salicylate (CAS: 2052-14-4) is a colorless to pale yellow liquid with a characteristic odor. It has a molecular weight of approximately 176.22 g/mol. This compound is soluble in organic solvents but has limited water solubility. It is relatively stable under normal conditions but can react with strong bases. Butyl salicylate is commonly used in perfumes and pharmaceuticals due to its pleasant scent and anti-inflammatory properties.

Butyl salicylate (CAS: 2052-14-4) is typically synthesized by esterification of salicylic acid with n-butanol in the presence of a strong acid catalyst, such as sulfuric acid or hydrochloric acid. The reaction is carried out under reflux conditions, and the mixture is then neutralized to obtain the desired product. The yield of the reaction is around 85-90%, and the method is selective towards the butyl ester formation.

Butyl salicylate (CAS: 2052-14-4) is widely used in the pharmaceutical industry for its anti-inflammatory and analgesic properties. It is also an important ingredient in fragrance formulations due to its pleasant scent. Additionally, it is utilized in the polymer industry for improving the mechanical properties of polymers and in the semiconductor industry for etching processes.

Butyl salicylate (CAS: 2052-14-4) should be handled with caution due to its potential skin and eye irritation. Protective gloves, goggles, and appropriate lab wear should be worn. Storage should be in a cool, well-ventilated area away from heat sources. In case of a spill, it should be cleaned up using appropriate absorbent materials. Always refer to the Material Safety Data Sheet (MSDS) for detailed safety information and emergency procedures.
