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 4-(4-(2-Chlorophenyl)-2-phenyloxazol-5-yl)-N,N-diethylaniline.
4-(4-(2-Chlorophenyl)-2-phenyloxazol-5-yl)-N,N-diethylaniline (CAS 55766-52-4) is a high-purity analytical reference standard with the molecular formula C25H23ClN2O and a molecular weight of 402.92 g/mol.
The molecular framework of 4-(4-(2-Chlorophenyl)-2-phenyloxazol-5-yl)-N,N-diethylaniline (C25H23ClN2O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 4-(4-(2-Chlorophenyl)-2-phenyloxazol-5-yl)-N,N-diethylaniline 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.
