Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Nitro-4-sulfamoylbenzoic acid.
2-Nitro-4-sulfamoylbenzoic acid (CAS 29092-31-7) is a high-purity analytical reference standard with the molecular formula C7H6N2O6S and a molecular weight of 246.20 g/mol.
Owing to a carbohydrate-derived structure, an amide group, a sulfone group, 2-Nitro-4-sulfamoylbenzoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 246.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-Nitro-4-sulfamoylbenzoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
