Chemical Structure

1-(4-nitro-1,2,5-oxadiazol-3-yl)ethanone CAS 159014-10-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(4-nitro-1,2,5-oxadiazol-3-yl)ethanone.

1-(4-nitro-1,2,5-oxadiazol-3-yl)ethanone (CAS 159014-10-5) is a high-purity analytical reference standard with the molecular formula C4H7N3O4 and a molecular weight of 161.12 g/mol.

The molecular framework of 1-(4-nitro-1,2,5-oxadiazol-3-yl)ethanone (C4H7N3O4) is characterized by a carbohydrate-derived structure, an amide group. 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. 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.

CATO manufactures 1-(4-nitro-1,2,5-oxadiazol-3-yl)ethanone under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
