Chemical Structure
Description
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.
3-(Chloromethyl)-5-(2-phenylethyl)-1,2,4-oxadiazole (CAS 1152498-72-0), molecular formula C11H11ClN2O and molecular weight 222.67 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 3-(Chloromethyl)-5-(2-phenylethyl)-1,2,4-oxadiazole is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 222.67 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
