Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-1-(3,5-Difluorophenyl)ethan-1-ol.
CATO supplies (S)-1-(3,5-Difluorophenyl)ethan-1-ol (CAS 692732-03-9), a certified reference material (molecular formula C8H8F2O, MW 158.15 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, (S)-1-(3,5-Difluorophenyl)ethan-1-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 158.15 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures (S)-1-(3,5-Difluorophenyl)ethan-1-ol 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.
