Chemical Structure
Description
CATO supplies 1-Ethyl-2-oxo-2,3-dihydro-1h-1,3-benzodiazole-5-carboxylic acid (CAS 99072-14-7), a certified reference material (molecular formula C10H10N2O3, MW 206.20 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 1-Ethyl-2-oxo-2,3-dihydro-1h-1,3-benzodiazole-5-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 206.20 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.
CATO manufactures 1-Ethyl-2-oxo-2,3-dihydro-1h-1,3-benzodiazole-5-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.
