Chemical Structure

(αS)-2-Chloro-4-fluoro-α-methyl-benzenemethanol CAS 911218-03-6 chemical structure

Description

(αS)-2-Chloro-4-fluoro-α-methyl-benzenemethanol (CAS 911218-03-6) is a high-purity analytical reference standard with the molecular formula C8H8ClFO and a molecular weight of 174.60 g/mol.

Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, (αS)-2-Chloro-4-fluoro-α-methyl-benzenemethanol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 174.60 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.

As a certified reference material (CRM), (αS)-2-Chloro-4-fluoro-α-methyl-benzenemethanol 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.
