2-(4-Chloro-2-methylphenoxy)-N-(4-chlorophenyl)-2,2-difluoroacetamide CAS 339010-93-4

Description

As a certified reference material (CRM), 2-(4-Chloro-2-methylphenoxy)-N-(4-chlorophenyl)-2,2-difluoroacetamide 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.

2-(4-Chloro-2-methylphenoxy)-N-(4-chlorophenyl)-2,2-difluoroacetamide (CAS 339010-93-4), molecular formula C15H11Cl2F2NO2 and molecular weight 346.16 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 2-(4-Chloro-2-methylphenoxy)-N-(4-chlorophenyl)-2,2-difluoroacetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 346.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
