CATO supplies 2-{4-[(5-ethyl-1,2,4-oxadiazol-3-yl)methyl]-1,4-diazepan-1-yl}-n-(5-methyl-1,2-oxazol-3-yl)acetamide (CAS 1376350-77-4), a certified reference material (molecular formula C16H24N6O3, MW 348.40 g/mol) for analytical method development and quality control.

2-{4-[(5-ethyl-1,2,4-oxadiazol-3-yl)methyl]-1,4-diazepan-1-yl}-n-(5-methyl-1,2-oxazol-3-yl)acetamide (C16H24N6O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
