3-[5-(Chloromethyl)-1,2,4-oxadiazol-3-yl]-4-methoxy-N-propylbenzamide CAS 1119450-86-0

Description

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.

3-[5-(Chloromethyl)-1,2,4-oxadiazol-3-yl]-4-methoxy-N-propylbenzamide (CAS 1119450-86-0) is a high-purity analytical reference standard with the molecular formula C14H16ClN3O3 and a molecular weight of 309.75 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 3-[5-(Chloromethyl)-1,2,4-oxadiazol-3-yl]-4-methoxy-N-propylbenzamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 309.75 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
