1,3-Dichloro-5-methyl-2-nitrobenzene CAS 89692-81-9

Description

The occurrence of 1,3-Dichloro-5-methyl-2-nitrobenzene is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1,3-Dichloro-5-methyl-2-nitrobenzene (CAS 89692-81-9), a certified reference material (molecular formula C7H5Cl2NO2, MW 206.03 g/mol) for analytical method development and quality control.

The molecular framework of 1,3-Dichloro-5-methyl-2-nitrobenzene (C7H5Cl2NO2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), 1,3-Dichloro-5-methyl-2-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.
