Chemical Structure
Description
The occurrence of 3-nitro-4-sulfamoylbenzoic acid is closely related to a carbohydrate-derived structure, an amide group, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-nitro-4-sulfamoylbenzoic acid (CAS 89795-76-6), molecular formula C7H6N2O6S and molecular weight 246.20 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carbohydrate-derived structure, an amide group, a sulfone group, 3-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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-nitro-4-sulfamoylbenzoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
