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.
O-(4-Nitrobenzoyl)hydroxylamine 35657-36-4 MFCD11976095 SY029700 (CAS 35657-36-4), molecular formula C7H12N2O4 and molecular weight 188.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of O-(4-Nitrobenzoyl)hydroxylamine 35657-36-4 MFCD11976095 SY029700 (C7H12N2O4) 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 O-(4-Nitrobenzoyl)hydroxylamine 35657-36-4 MFCD11976095 SY029700 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.
