Betahistine mesylate(CAS: 54856-23-4)

Betahistine mesylate is a white or practically white crystalline powder. It has a molecular weight of approximately 418.5 g/mol and a high solubility in water. It is relatively stable under normal conditions but can undergo hydrolysis in the presence of water and acid. It is used in the treatment of vertigo and other symptoms of inner ear disorders.

Betahistine mesylate is synthesized through an acylation reaction of betahistine with methanesulfonyl chloride. The reaction is typically performed in the presence of a base such as triethylamine. The product is then purified by recrystallization. This method provides good selectivity and yields up to 95%.

Betahistine mesylate (CAS: 54856-23-4) is primarily used in the pharmaceutical industry for the treatment of vertigo and other inner ear disorders. It is also used in the cosmetics industry for its vasodilatory properties.

When handling Betahistine mesylate (CAS: 54856-23-4), it is important to use personal protective equipment such as gloves and goggles to protect against skin and eye contact. Handling should be carried out in a fume hood to avoid inhalation. Spills should be cleaned up using appropriate absorbent materials and the area should be ventilated. Always refer to the Material Safety Data Sheet (MSDS) for detailed safety information.
