Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(2,4-Difluoro-5-(trifluoromethyl)phenyl)methanol (CAS 1936257-01-0), molecular formula C8H5F5O and molecular weight 212.12 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2,4-Difluoro-5-(trifluoromethyl)phenyl)methanol (C8H5F5O) is characterized by a hydroxyl group, an ether linkage, fluorine 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.
As a certified reference material (CRM), (2,4-Difluoro-5-(trifluoromethyl)phenyl)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.
