2-hydroxy-1-naphthalenecarboxylic acid methyl ester - Introduction
Methyl 2-hydroxy-1-naphthoate is an organic compound with the chemical formula C13H10O3.
Nature:
Methyl 2-hydroxy-1-naphthoate is a white or pale yellow crystalline powder. It is almost insoluble in water, but soluble in organic solvents such as ethanol and ether. It is relatively stable at room temperature.
Use:
Methyl 2-hydroxy-1-naphthoate is widely used as an intermediate in organic synthesis. It can be used in the preparation of various fragrances and cosmetics, such as soaps, perfumes and skin care products, for imparting a specific odor to products.
Preparation Method:
Methyl 2-hydroxy-1-naphthoate is typically synthesized by an esterification reaction. The specific step is to react 1-hydroxy-2-naphthoic acid and methanol under acidic conditions to generate Methyl 2-hydroxy-1-napthoate.
Safety Information:
Methyl 2-hydroxy-1-napthoate has low acute toxicity, but long-term exposure may cause irritation to the skin and eyes. Care should be taken to avoid skin contact and inhalation during handling. Wear appropriate protective equipment such as gloves, goggles, and respiratory protectors during operation.
