N-(5-(5,6-Dihydro-1,4-dioxin-2-yl)-1,3,4-oxadiazol-2-yl)furan-2-carboxamide CAS 887875-45-8

Description

The molecular framework of N-(5-(5,6-Dihydro-1,4-dioxin-2-yl)-1,3,4-oxadiazol-2-yl)furan-2-carboxamide (C11H9N3O5) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

N-(5-(5,6-Dihydro-1,4-dioxin-2-yl)-1,3,4-oxadiazol-2-yl)furan-2-carboxamide (CAS 887875-45-8), molecular formula C11H9N3O5 and molecular weight 263.21 g/mol, is a CATO reference standard with documented purity and traceability.

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.
