Chemical Structure
Description
CATO supplies (R)-3-Methyl-5-(7-(4-(4-methyl-4,5-dihydrooxazol-2-yl)phenoxy)heptyl)isoxazole (CAS 98524-87-9), a certified reference material (molecular formula C21H28N2O3, MW 356.46 g/mol) for analytical method development and quality control.
The molecular framework of (R)-3-Methyl-5-(7-(4-(4-methyl-4,5-dihydrooxazol-2-yl)phenoxy)heptyl)isoxazole (C21H28N2O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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 (R)-3-Methyl-5-(7-(4-(4-methyl-4,5-dihydrooxazol-2-yl)phenoxy)heptyl)isoxazole 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.
