Chemical Structure

1-Chloro-2-fluoro-3-methoxy-5-(trifluoromethyl)benzene CAS 261763-01-3 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-fluoro-3-methoxy-5-(trifluoromethyl)benzene.

CATO supplies 1-Chloro-2-fluoro-3-methoxy-5-(trifluoromethyl)benzene (CAS 261763-01-3), a certified reference material (molecular formula C8H5ClF4O, MW 228.57 g/mol) for analytical method development and quality control.

Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 1-Chloro-2-fluoro-3-methoxy-5-(trifluoromethyl)benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 228.57 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
