Description
CATO manufactures 2,3-Diphenylquinoxaline-6-carboxylic Acid 2-Hydroxyethyl Amide 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.
2,3-Diphenylquinoxaline-6-carboxylic Acid 2-Hydroxyethyl Amide (CAS 332404-53-2) is a high-purity analytical reference standard with the molecular formula C23H19N3O2 and a molecular weight of 369.42 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 2,3-Diphenylquinoxaline-6-carboxylic Acid 2-Hydroxyethyl Amide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 369.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
