Chemical Structure
Description
The occurrence of 3-Nitro-2-(phenylsulfanyl)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.
CATO supplies 3-Nitro-2-(phenylsulfanyl)benzoic acid (CAS 13421-12-0), a certified reference material (molecular formula C13H9NO4S, MW 275.28 g/mol) for analytical method development and quality control.
3-Nitro-2-(phenylsulfanyl)benzoic acid (C13H9NO4S) 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. 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.
