2-(chloromethyl)-1-fluoro-4-methylbenzene CAS 64977-31-7 chemical structure

Description

As a certified reference material (CRM), 2-(chloromethyl)-1-fluoro-4-methylbenzene 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.

2-(chloromethyl)-1-fluoro-4-methylbenzene (CAS 64977-31-7), molecular formula C8H8ClF and molecular weight 158.60 g/mol, is a CATO reference standard with documented purity and traceability.

2-(chloromethyl)-1-fluoro-4-methylbenzene (C8H8ClF) contains fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
