Chemical Structure
Description
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 supplies 3-Chloro-4-fluoro-N-phenethylaniline (CAS 940366-17-6), a certified reference material (molecular formula C14H13ClFN, MW 249.71 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution, 3-Chloro-4-fluoro-N-phenethylaniline is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 249.71 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).
As a certified reference material (CRM), 3-Chloro-4-fluoro-N-phenethylaniline 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.
