2,2-Dimethyl-7-nitro-2H-benzo[b][1,4]oxazin-3(4H)-one CAS 85160-83-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2-Dimethyl-7-nitro-2H-benzo[b][1,4]oxazin-3(4H)-one.

CATO supplies 2,2-Dimethyl-7-nitro-2H-benzo[b][1,4]oxazin-3(4H)-one (CAS 85160-83-4), a certified reference material (molecular formula C10H10N2O4, MW 222.20 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, 2,2-Dimethyl-7-nitro-2H-benzo[b][1,4]oxazin-3(4H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 222.20 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 2,2-Dimethyl-7-nitro-2H-benzo[b][1,4]oxazin-3(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.
