2-(2-((5-Amino-1H-1,2,4-triazol-3-yl)thio)ethyl)isoindoline-1,3-dione CAS 728901-60-8 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 2-(2-((5-Amino-1H-1,2,4-triazol-3-yl)thio)ethyl)isoindoline-1,3-dione.

2-(2-((5-Amino-1H-1,2,4-triazol-3-yl)thio)ethyl)isoindoline-1,3-dione (CAS 728901-60-8) is a high-purity analytical reference standard with the molecular formula C12H11N5O2S and a molecular weight of 289.31 g/mol.

The molecular framework of 2-(2-((5-Amino-1H-1,2,4-triazol-3-yl)thio)ethyl)isoindoline-1,3-dione (C12H11N5O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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 2-(2-((5-Amino-1H-1,2,4-triazol-3-yl)thio)ethyl)isoindoline-1,3-dione 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.
