4-Cyclopropyl-1-naphthalenamine hydrochloride (1:1)(CAS: 1533519-92-4)

4-Cyclopropyl-1-naphthalenamine hydrochloride is a crystalline solid with a molecular weight of approximately 248.8 g/mol. It is slightly soluble in water and more soluble in organic solvents. The compound is reactive towards basic conditions and has a pKa of around 17. It is stable under normal laboratory conditions but should be stored in a dry, cool place to avoid hydrolysis.

4-Cyclopropyl-1-naphthalenamine hydrochloride can be synthesized through the reaction of 1-naphthalenamine with cyclopropyl bromide in the presence of a base, such as sodium hydride. The yield is generally good, and the product can be purified by recrystallization from an appropriate solvent. The reaction is usually conducted under an inert atmosphere to prevent side reactions.

4-Cyclopropyl-1-naphthalenamine hydrochloride is used in the pharmaceutical industry as a precursor for drug synthesis. It is also used in the sensor industry for the development of gas sensors, particularly for detecting specific gases. Additionally, this compound can be found in the semiconductor industry as a dopant material.

When handling 4-Cyclopropyl-1-naphthalenamine hydrochloride, it is essential to use appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. Handle the compound in a well-ventilated area or a fume hood to avoid inhalation. Spills should be cleaned up immediately using an appropriate solvent, and the area should be well-ventilated. Refer to the Safety Data Sheet (SDS) for detailed instructions and emergency protocols.
