Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(3-Methyl-4-(trifluoromethyl)phenyl)methanol (CAS 957205-74-2), molecular formula C9H9F3O and molecular weight 190.16 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, (3-Methyl-4-(trifluoromethyl)phenyl)methanol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 190.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), (3-Methyl-4-(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.
