Chemical Structure
Description
2-(3-Nitrobenzoyl)benzoic acid (CAS 2159-38-8) is a high-purity analytical reference standard with the molecular formula C16H16N2O5S2 and a molecular weight of 380.44 g/mol.
2-(3-Nitrobenzoyl)benzoic acid (C16H16N2O5S2) contains a flavonoid core, 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).
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 2-(3-Nitrobenzoyl)benzoic 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.
