AboutCongo Red
Congo Red (CAS 573-58-0) is a sodium salt of benzidinediazo-bis-1-naphthylamine-4-sulfonic acid. It appears as a dark red to brown powder and is highly soluble in water, forming a colloidal solution that changes color from blue to red across a specific pH range.
In the Indian market, this chemical is predominantly sourced by diagnostic laboratories for amyloid detection and by textile mills for specific dyeing applications. Its role as a pH indicator makes it a staple in academic and industrial chemical testing facilities across the country.
When procuring Congo Red, buyers should prioritize suppliers providing a Certificate of Analysis (COA) confirming dye content and purity levels. Given its classification as a potential carcinogen, industrial buyers must ensure compliance with safety protocols during handling and storage.
