Description
CATO manufactures 1,3-Bis((S)-4-(tert-butyl)-4,5-dihydrooxazol-2-yl)benzene 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.
1,3-Bis((S)-4-(tert-butyl)-4,5-dihydrooxazol-2-yl)benzene (CAS 196207-68-8), molecular formula C20H28N2O2 and molecular weight 328.45 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,3-Bis((S)-4-(tert-butyl)-4,5-dihydrooxazol-2-yl)benzene (C20H28N2O2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
