Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3-(2,5-Difluorophenyl)-5-methylisoxazol-4-yl)methanol.
(3-(2,5-Difluorophenyl)-5-methylisoxazol-4-yl)methanol (CAS 1159602-56-8) is a high-purity analytical reference standard with the molecular formula C11H9F2NO2 and a molecular weight of 225.19 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, (3-(2,5-Difluorophenyl)-5-methylisoxazol-4-yl)methanol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 225.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 (3-(2,5-Difluorophenyl)-5-methylisoxazol-4-yl)methanol 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.
