About phenol or phenol-alcohol derivatives, sulphonated, nitrated or nitrosated derivatives thereof; 4,6-dinitro-o-cresol (dnoc (iso)) and its salts

HS code 290892 covers a range of chemical compounds derived from phenol or phenol-alcohol, including sulphonated, nitrated, or nitrosated derivatives. These substances are widely used in various industries, such as pharmaceuticals, agrochemicals, and specialty chemicals, making them an important part of the broader chemical industry. Their versatility and diverse applications contribute significantly to the global economy.

Production process

The production of the chemicals covered under HS code 290892 typically involves a series of chemical reactions and purification processes. The starting point is often the extraction or synthesis of phenol or phenol-alcohol, which is then subjected to sulphonation, nitration, or nitrosation reactions to create the desired derivatives. These processes may involve the use of specialized catalysts, solvents, and reaction conditions to optimize the yield and purity of the final products.

Production inputs

The main inputs required for the production of the chemicals under HS code 290892 include phenol or phenol-alcohol as the primary raw material, as well as various reagents and solvents used in the sulphonation, nitration, or nitrosation reactions. Additionally, specialized equipment, such as reactors, distillation columns, and purification systems, are necessary to ensure the efficient and high-quality production of these chemicals.

Production outputs

The chemicals produced under HS code 290892 are used as intermediates or building blocks in the manufacture of a wide range of products, including 300490 (Medicaments (excluding goods of heading 30.02, 30.05 or 30.06) 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), 380899 (Pesticides 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 various specialty chemicals. These derivatives find applications in the pharmaceutical, agrochemical, and other industries.
