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 5-(4-(3-Bromo-4-methylphenyl)-2-methoxypyrimidin-5-yl)-3-methylisoxazole.
5-(4-(3-Bromo-4-methylphenyl)-2-methoxypyrimidin-5-yl)-3-methylisoxazole (CAS 1233025-41-6), molecular formula C16H14BrN3O2 and molecular weight 360.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(4-(3-Bromo-4-methylphenyl)-2-methoxypyrimidin-5-yl)-3-methylisoxazole (C16H14BrN3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 5-(4-(3-Bromo-4-methylphenyl)-2-methoxypyrimidin-5-yl)-3-methylisoxazole 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.
