Chemical Structure
Description
CATO manufactures sodium 3-nitrobenzenesulfonate 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.
CATO supplies sodium 3-nitrobenzenesulfonate (CAS 127-68-4), a certified reference material (molecular formula C6H4NO5SNa, MW 225.15 g/mol) for analytical method development and quality control.
Owing to a carbohydrate-derived structure, an amide group, a sulfone group, sodium 3-nitrobenzenesulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 225.15 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.
