Chemical Structure
Description
The molecular framework of Benzo[c][1,2,5]oxadiazole-5-carbohydrazide (C7H6N4O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Benzo[c][1,2,5]oxadiazole-5-carbohydrazide (CAS 175203-93-7) is a high-purity analytical reference standard with the molecular formula C7H6N4O2 and a molecular weight of 178.15 g/mol.
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.
