Chemical Structure

1-Chloro-2-[chloro(difluoro)-methoxy]-4-nitro-benzene CAS 1417569-58-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Chloro-2-[chloro(difluoro)-methoxy]-4-nitro-benzene.

1-Chloro-2-[chloro(difluoro)-methoxy]-4-nitro-benzene (CAS 1417569-58-4) is a high-purity analytical reference standard with the molecular formula C7H3Cl2F2NO3 and a molecular weight of 258.01 g/mol.

The molecular framework of 1-Chloro-2-[chloro(difluoro)-methoxy]-4-nitro-benzene (C7H3Cl2F2NO3) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 1-Chloro-2-[chloro(difluoro)-methoxy]-4-nitro-benzene 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.
