Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
6-Nitro-1H-benzo[d][1,3]oxazin-2(4H)-one (CAS 94107-60-5) is a high-purity analytical reference standard with the molecular formula C8H6N2O4 and a molecular weight of 194.14 g/mol.
The molecular framework of 6-Nitro-1H-benzo[d][1,3]oxazin-2(4H)-one (C8H6N2O4) 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 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).
CATO manufactures 6-Nitro-1H-benzo[d][1,3]oxazin-2(4H)-one 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.
