3-Nitrobenzo[b]thiophene (NBT) is an organic compound that is commonly used as a starting material in the production of various chemicals and materials.
In the chemical industry, NBT is considered an upstream product, which means it is a raw material used in the production of downstream products.
Downstream products are the end products that are derived from the upstream products through a series of chemical reactions and processes.

One of the most common downstream products derived from NBT is 3-nitro-4-phenyl-5-sulfonamide, which is used as an intermediate in the production of dyes, pigments, and other chemical products.
This compound is synthesized by reacting NBT with chlorosulfonic acid and sodium chloride, followed by purification and recrystallization.

Another downstream product derived from NBT is 3-nitro-4-(phenylsulfonyl)benzene-1,2-diamine, which is used in the production of lubricants and additives for fuels.
This compound is synthesized by reacting NBT with sulfuric acid, followed by condensation with aromatic diamin
