Imines and their derivatives; salts thereof; chlordimeform (ISO)

HS code 292521 covers a group of organic compounds known as imines and their derivatives, including salts and the pesticide chlordimeform. Imines are a class of nitrogen-containing compounds that play a crucial role in various industries, from pharmaceuticals to agrochemicals. This code represents an important segment of the broader organic chemicals industry, which is a vital component of the global economy, enabling the production of a wide range of essential products.

The production of imines and their derivatives typically involves the condensation reaction between a primary amine and an aldehyde or ketone. This process is often catalyzed by acids or bases to facilitate the formation of the imine bond. Chlordimeform, a specific compound within this code, is synthesized through the reaction of 4-chloro-o-toluidine with dimethylformamide.

The main inputs required for the production of imines and their derivatives under HS code 292521 include various primary amines, aldehydes, and ketones, as well as catalysts and solvents. Additionally, specialized equipment such as reactors, distillation columns, and purification systems are necessary for the manufacturing process.

The outputs of HS code 292521 include a diverse range of imine compounds and their derivatives, which find applications in the pharmaceutical, agrochemical, and specialty chemicals industries. These products may be further processed or incorporated into the production of 300490 (Medicaments (excluding goods of heading 3002, 3005 or 3006) consisting of mixed or unmixed products for therapeutic or prophylactic uses, put up in measured doses (including those in the form of transdermal administration systems) or in forms or packings for retail sale), 380810 (Insecticides, rodenticides, fungicides, herbicides, anti-sprouting products and plant-growth regulators, disinfectants and similar products, put up in forms or packings for retail sale or as preparations or articles (for example, sulphur-treated bands, wicks and candles, and fly-papers)), and other related HS codes.
