Chemical Structure

(1-Chloroethyl)benzene CAS 672-65-1 chemical structure

Description

As a certified reference material (CRM), (1-Chloroethyl)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.

CATO supplies (1-Chloroethyl)benzene (CAS 672-65-1), a certified reference material (molecular formula C8H9Cl, MW 140.61 g/mol) for analytical method development and quality control.

The molecular framework of (1-Chloroethyl)benzene (C8H9Cl) is characterized by chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
