Chemical Structure
Description
(5-Chloro-2-fluoro-4-methylphenyl)methanol (CAS 252004-44-7) is a high-purity analytical reference standard with the molecular formula C8H8ClFO and a molecular weight of 174.60 g/mol.
(5-Chloro-2-fluoro-4-methylphenyl)methanol (C8H8ClFO) contains a hydroxyl group, an ether linkage, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (5-Chloro-2-fluoro-4-methylphenyl)methanol 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.
