Chemical Structure
Description
CATO supplies 3-Methyl-5-nitrobenzofuran-2-carboxylic acid (CAS 87977-34-2), a certified reference material (molecular formula C10H7NO5, MW 221.17 g/mol) for analytical method development and quality control.
3-Methyl-5-nitrobenzofuran-2-carboxylic acid (C10H7NO5) contains an amino-acid-derived structure, an amide 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 3-Methyl-5-nitrobenzofuran-2-carboxylic acid 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.
