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 1-Chloro-2,3-dimethyl-4-(1-phenylethyl)benzene (CAS 95719-24-7), a certified reference material (molecular formula C16H17Cl, MW 244.76 g/mol) for analytical method development and quality control.
Owing to chlorine substitution, a polycyclic aromatic system, 1-Chloro-2,3-dimethyl-4-(1-phenylethyl)benzene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 244.76 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.
As a certified reference material (CRM), 1-Chloro-2,3-dimethyl-4-(1-phenylethyl)benzene 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.
