Chemical Structure
Description
The molecular framework of (5-Methyl-1,3,4-oxadiazol-2-yl)methanamine oxalate (C4H7N3OC2H2O4) 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.
(5-Methyl-1,3,4-oxadiazol-2-yl)methanamine oxalate (CAS 1187931-57-2), molecular formula C4H7N3OC2H2O4 and molecular weight 203.15 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.
