Chemical Structure
Description
Potassium 5-(methoxymethyl)-1,2,4-oxadiazole-3-carboxylate (CAS 1607281-07-1) is a high-purity analytical reference standard with the molecular formula C5H5N2O4K and a molecular weight of 196.20 g/mol.
The molecular framework of Potassium 5-(methoxymethyl)-1,2,4-oxadiazole-3-carboxylate (C5H5N2O4K) 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 Potassium 5-(methoxymethyl)-1,2,4-oxadiazole-3-carboxylate 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.
