Chemical Structure
Description
CATO supplies (R)-(5-(Chloromethyl)-1,3,4-oxadiazol-2-yl)(cyclohexyl)(phenyl)methanol (CAS 1208254-99-2), a certified reference material (molecular formula C16H19ClN2O2, MW 306.79 g/mol) for analytical method development and quality control.
The molecular framework of (R)-(5-(Chloromethyl)-1,3,4-oxadiazol-2-yl)(cyclohexyl)(phenyl)methanol (C16H19ClN2O2) is characterized by a nitrogen-containing heterocyclic scaffold, 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. 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).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
