Chemical Structure
Description
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 supplies 1-(2-Aminobenzo[d]oxazol-4-yl)ethanone (CAS 1807067-17-9), a certified reference material (molecular formula C9H8N2O2, MW 176.17 g/mol) for analytical method development and quality control.
1-(2-Aminobenzo[d]oxazol-4-yl)ethanone (C9H8N2O2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 1-(2-Aminobenzo[d]oxazol-4-yl)ethanone meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
