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 Ethyl (5-oxo-2,5-dihydro-1,2,4-oxadiazol-3-yl)carbamate.
CATO supplies Ethyl (5-oxo-2,5-dihydro-1,2,4-oxadiazol-3-yl)carbamate (CAS 154020-16-3), a certified reference material (molecular formula C5H7N3O4, MW 173.13 g/mol) for analytical method development and quality control.
Structurally, Ethyl (5-oxo-2,5-dihydro-1,2,4-oxadiazol-3-yl)carbamate (C5H7N3O4) contains a carbohydrate-derived structure, an amide group. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 173.13 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 Ethyl (5-oxo-2,5-dihydro-1,2,4-oxadiazol-3-yl)carbamate 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.
