Methyl L-cysteinate hydrochloride (1:1)(CAS: 18598-63-5)

Methyl L-cysteinate hydrochloride is a white or off-white crystalline powder. Its molecular weight is approximately 254.76 g/mol. It is soluble in water and slightly soluble in ethanol. The compound is relatively stable under normal conditions but can react with bases to form cysteine. It is used in pharmaceutical applications and has low reactivity under typical storage conditions.

Methyl L-cysteinate hydrochloride is synthesized by reacting L-cysteine with methylamine hydrochloride, followed by hydrolysis and acidification. Commonly, sodium hydroxide is used as a catalyst to ensure high selectivity and yield. The reaction is typically performed in aqueous solution at room temperature.

Methyl L-cysteinate hydrochloride is primarily used in the pharmaceutical industry for its potential anti-inflammatory and analgesic properties. It is also explored for its applications in sensor technology due to its reactivity with certain analytes, making it suitable for detection and monitoring purposes.

Precautions include wearing appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Handling should be done in a fume hood to minimize inhalation risks. Spills should be promptly addressed with appropriate absorbents, and the area should be cleaned thoroughly. Always refer to the Safety Data Sheet (SDS) for detailed handling and disposal information.
