About sulphonamides

HS code 2935 covers the classification of sulphonamides, a class of organic compounds that have played a significant role in the pharmaceutical industry for over a century. Sulphonamides are synthetic drugs that exhibit a wide range of therapeutic properties, including antimicrobial, diuretic, and anti-inflammatory effects. These compounds have been instrumental in the treatment of various bacterial infections, as well as in the management of conditions such as hypertension and certain types of cancer. The sulphonamide industry is an integral part of the broader pharmaceutical and chemical sectors, contributing to the development of essential medicines and the overall well-being of populations worldwide.

Production process

The production of sulphonamides typically involves a multi-step chemical synthesis process. The key steps often include the reaction of an aromatic amine with a sulfonyl chloride, followed by further modifications to introduce various functional groups and achieve the desired therapeutic properties. The specific techniques employed may vary depending on the target sulphonamide compound, but generally involve the use of common organic chemistry methods, such as condensation, substitution, and oxidation reactions.

Production inputs

The main inputs required for the production of sulphonamides include aromatic amines, sulfonyl chlorides, and other organic reagents and solvents. Additionally, specialized equipment, such as chemical reactors, distillation columns, and purification systems, are necessary to carry out the various synthesis steps and ensure the quality of the final products. The industry also relies on a skilled workforce with expertise in organic chemistry, pharmaceutical manufacturing, and quality control.

Production outputs

The primary outputs of the sulphonamide industry are the various sulphonamide compounds, which are then used as active pharmaceutical ingredients (APIs) in the production of a wide range of medications. These medications may be classified under different HS codes, such as 3004 Medicamentsand 3002 Antisera, vaccines, toxins and microbiological products.
