Description
CATO manufactures 2-Formyl-3,4,5-trihydroxybenzoic 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.
2-Formyl-3,4,5-trihydroxybenzoic acid (CAS 82297-94-7) is a high-purity analytical reference standard with the molecular formula C8H6O6 and a molecular weight of 198.13 g/mol.
2-Formyl-3,4,5-trihydroxybenzoic acid (C8H6O6) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
