5-Amino-N-hydroxy-1,2,4-oxadiazole-3-carboximidamide CAS 371935-95-4

Description

The occurrence of 5-Amino-N-hydroxy-1,2,4-oxadiazole-3-carboximidamide is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Amino-N-hydroxy-1,2,4-oxadiazole-3-carboximidamide (CAS 371935-95-4) is a high-purity analytical reference standard with the molecular formula C3H5N5O2 and a molecular weight of 143.10 g/mol.

5-Amino-N-hydroxy-1,2,4-oxadiazole-3-carboximidamide (C3H5N5O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
