4-(5-(5-Chlorothiophen-2-yl)-1H-1,2,3-triazol-1-yl)-1,2,5-oxadiazol-3-amine CAS 890093-93-3 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 4-(5-(5-Chlorothiophen-2-yl)-1H-1,2,3-triazol-1-yl)-1,2,5-oxadiazol-3-amine.

4-(5-(5-Chlorothiophen-2-yl)-1H-1,2,3-triazol-1-yl)-1,2,5-oxadiazol-3-amine (CAS 890093-93-3), molecular formula C8H5ClN6OS and molecular weight 268.68 g/mol, is a CATO reference standard with documented purity and traceability.

4-(5-(5-Chlorothiophen-2-yl)-1H-1,2,3-triazol-1-yl)-1,2,5-oxadiazol-3-amine (C8H5ClN6OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, 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.

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.
