2-Chloro-4-fluoro-1-methyl-3-nitrobenzene CAS 1805115-44-9

Description

Compared with other compounds in its class, the molecular weight of 189.57 g/mol gives 2-Chloro-4-fluoro-1-methyl-3-nitrobenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Chloro-4-fluoro-1-methyl-3-nitrobenzene (CAS 1805115-44-9), molecular formula C7H5ClFNO2 and molecular weight 189.57 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Chloro-4-fluoro-1-methyl-3-nitrobenzene (C7H5ClFNO2) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), 2-Chloro-4-fluoro-1-methyl-3-nitrobenzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
