Usage

General Description

Methyl 2-amino-3-methylbenzoate, also known as methyl anthranilate, is a clear to pale yellow liquid with a fruity, grape-like odor. It is commonly used as a flavoring agent in the food and beverage industry, particularly in grape and orange-flavored products. It is also used in the fragrance industry as a component in perfumes and as an insect repellent. Additionally, it has been found to have potential as an anti-inflammatory and analgesic agent, making it a subject of interest in pharmaceutical research. However, it is important to handle this chemical with care as it can cause eye and skin irritation, and is harmful if swallowed or inhaled in large amounts.

Method for synthesizing chlorantraniliprole

A solvent containing 2 - amino -3 - methylbenzoic acid is stirred, N - methyl -3 - methyl -2 - amino - benzamide is dissolved in alkali liquor in a stirring reaction process, and reacted with NCS to obtain N - methyl -3 - methyl -2 - amino -5 - chloro - benzamide. The reaction of the bromination reaction, the oxidation reaction and the condensation reaction is carried out by cooperation of a catalyst so as to obtain chlorantraniliprole. By optimizing the preparation steps of chlorantraniliprole, the whole process is relatively simple in process steps, the post-treatment is simple, intermediate products can be obtained directly after the single step is finished, high environmental control requirements are not needed in the whole synthesis step, and industrialization can be conveniently realized.
