Chemical Structure
Description
The occurrence of 4-Methanesulfonyl-3-nitro-benzoic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Methanesulfonyl-3-nitro-benzoic acid (CAS 81029-08-5) is a high-purity analytical reference standard with the molecular formula C8H7NO6S and a molecular weight of 245.21 g/mol.
4-Methanesulfonyl-3-nitro-benzoic acid (C8H7NO6S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 4-Methanesulfonyl-3-nitro-benzoic 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.
