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.
1-(Chloromethyl)-2-fluoro-4-methylbenzene (CAS 147541-99-9), molecular formula C8H8ClF and molecular weight 158.60 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine/chlorine substitution, an aromatic ring system, 1-(Chloromethyl)-2-fluoro-4-methylbenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 158.60 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.
CATO manufactures 1-(Chloromethyl)-2-fluoro-4-methylbenzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
