(R)-1-(p-Tolyl)ethanamine hydrochloride(CAS: 404336-49-8)

(R)-1-(p-Tolyl)ethanamine hydrochloride is a white crystalline solid with a molecular weight of approximately 225.7 g/mol. It has a pKa of about 1.7 and is soluble in water and ethanol. This compound is reactive with bases, making it an amine salt that can participate in various chemical reactions. It is stable under normal conditions but should be stored away from moisture and heat to prevent degradation.

(R)-1-(p-Tolyl)ethanamine hydrochloride can be synthesized via a multi-step process involving the formation of (R)-1-(p-tolyl)ethanamine followed by its reaction with hydrochloric acid to form the salt. Commonly, this involves a Grignard reaction of p-tolylmagnesium bromide with ethyl chloride, followed by quenching with an amine. The resulting amine is then treated with hydrochloric acid to yield the hydrochloride salt.

(R)-1-(p-Tolyl)ethanamine hydrochloride is primarily used in the pharmaceutical industry as an intermediate for the synthesis of various drug molecules. It is also used in the production of certain polymers and sensors due to its chemical reactivity and functional groups. Its use in semiconductors is less common but possible due to its potential as a dopant or precursor.

When handling (R)-1-(p-Tolyl)ethanamine hydrochloride, wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work in a well-ventilated area or fume hood to minimize exposure to vapors. Follow standard laboratory safety procedures and keep the compound away from moisture and heat. In case of a spill, absorb with appropriate materials and dispose of according to local regulations. Always refer to the Safety Data Sheet (SDS) for detailed handling and storage information.
