Chemical Structure
Description
CATO supplies Benzo[c][1,2,5]oxadiazole-5-carbaldehyde (CAS 32863-33-5), a certified reference material (molecular formula C7H4N2O2, MW 148.12 g/mol) for analytical method development and quality control.
Benzo[c][1,2,5]oxadiazole-5-carbaldehyde (C7H4N2O2) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
