1-Chloro-2-(difluoromethoxy)-4-nitrobenzene CAS 40319-62-8 chemical structure

Description

CATO manufactures 1-Chloro-2-(difluoromethoxy)-4-nitrobenzene 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.

1-Chloro-2-(difluoromethoxy)-4-nitrobenzene (CAS 40319-62-8), molecular formula C7H4ClF2NO3 and molecular weight 223.56 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-Chloro-2-(difluoromethoxy)-4-nitrobenzene (C7H4ClF2NO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 223.56 g/mol, it falls into the medium-molecular-weight range. 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.
