Methyl 4-hydroxy-3-sulfamoylbenzoate CAS 82020-63-1

Description

Compared with other compounds in its class, the molecular weight of 231.23 g/mol gives Methyl 4-hydroxy-3-sulfamoylbenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Methyl 4-hydroxy-3-sulfamoylbenzoate (CAS 82020-63-1), molecular formula C8H9NO5S and molecular weight 231.23 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Methyl 4-hydroxy-3-sulfamoylbenzoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.23 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), Methyl 4-hydroxy-3-sulfamoylbenzoate 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.
