Chemical Structure
Description
CATO supplies (4R)-4,5-Dihydro-2-(1-naphthalenyl)-4-phenyloxazole (CAS 936949-74-5), a certified reference material (molecular formula C19H15NO, MW 273.33 g/mol) for analytical method development and quality control.
The molecular framework of (4R)-4,5-Dihydro-2-(1-naphthalenyl)-4-phenyloxazole (C19H15NO) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures (4R)-4,5-Dihydro-2-(1-naphthalenyl)-4-phenyloxazole 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.
