Chemical Structure

5-Amino-3-(1-methylethyl)-1,2,3-oxadiazolium, inner salt hydrochloride CAS 5123-98-8 chemical structure

Description

CATO supplies 5-Amino-3-(1-methylethyl)-1,2,3-oxadiazolium, inner salt hydrochloride (CAS 5123-98-8), a certified reference material (molecular formula C5H9N3OHCl, MW 163.60 g/mol) for analytical method development and quality control.

5-Amino-3-(1-methylethyl)-1,2,3-oxadiazolium, inner salt hydrochloride (C5H9N3OHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; 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.

As a certified reference material (CRM), 5-Amino-3-(1-methylethyl)-1,2,3-oxadiazolium, inner salt hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
