Chemical Structure

4-Nitrosobenzonitrile CAS 31125-07-2 chemical structure

Description

The molecular framework of 4-Nitrosobenzonitrile (C7H4N2O) is characterized by an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).

4-Nitrosobenzonitrile (CAS 31125-07-2) is a high-purity analytical reference standard with the molecular formula C7H4N2O and a molecular weight of 132.12 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.

CATO manufactures 4-Nitrosobenzonitrile 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.
