4-[2-(Methylamino)ethyl]phenol hydrochloride (1:1)(CAS: 13062-76-5)

4-[2-(Methylamino)ethyl]phenol hydrochloride is a white crystalline solid with a molecular weight of approximately 261.7 g/mol. It is slightly soluble in water and has a basic pH. The compound is stable under normal conditions but can react with strong acids to regenerate the free base. It is used in various applications due to its hydrophilic properties and basic nature.

4-[2-(Methylamino)ethyl]phenol hydrochloride is typically synthesized by reacting 4-aminophenol with ethyl bromide in the presence of a base like sodium ethoxide. The reaction yields the hydrochloride salt of the compound with good selectivity and yield. The reaction is usually carried out in a solvent like ethanol and requires careful control of pH and temperature to ensure product quality.

4-[2-(Methylamino)ethyl]phenol hydrochloride is used in the pharmaceutical industry for the preparation of certain drugs, in the polymer industry as a modifier, and in the manufacturing of sensors and semiconductors due to its hydrophilic nature and basic properties. It is also used in some cosmetic applications.

When handling 4-[2-(Methylamino)ethyl]phenol hydrochloride, it is important to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. The substance should be handled in a well-ventilated area or a fume hood to avoid inhalation of dust or vapor. Spills should be cleaned up with appropriate absorbent materials and disposed of according to local regulations. Always refer to the safety data sheet (SDS) for detailed handling instructions and emergency procedures.
