What is Dapsone API
Chemical Identity and Classification
Dapsone, also known as 4,4'-diaminodiphenyl sulfone, is a synthetic antimicrobial agent belonging to the sulfone class. It works by inhibiting bacterial synthesis of folic acid, effectively preventing bacterial growth and replication.
In practical terms, Dapsone acts like a barrier that blocks bacteria from multiplying, helping the immune system eliminate infections more efficiently. This makes it highly effective in treating diseases such as leprosy and certain skin conditions.
Additionally, its anti-inflammatory properties make it useful in managing autoimmune skin disorders. This versatility is one of the reasons why pharmaceutical Dapsone manufacturer suppliers are in high demand globally.
Key Chemical / Technical Information
Molecular Structure and Formula
Dapsone has a molecular formula of C12H12N2O2S and a molecular weight of approximately 248.30 g/mol. Its structure consists of two aromatic rings linked by a sulfone group, which contributes to its stability and biological activity.
CAS Number and Identification
- CAS Number: 80-08-0
- IUPAC Name: 4-[(4-aminophenyl)sulfonyl]aniline
These identifiers are essential for regulatory documentation and quality verification in pharmaceutical manufacturing. Reliable bulk Dapsone manufacturer suppliers in India ensure that every batch meets these exact specifications.
