2-((5H-[1,2,4]triazino[5,6-b]indol-3-yl)thio)acetonitrile CAS 332110-24-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((5H-[1,2,4]triazino[5,6-b]indol-3-yl)thio)acetonitrile.

2-((5H-[1,2,4]triazino[5,6-b]indol-3-yl)thio)acetonitrile (CAS 332110-24-4), molecular formula C11H7N5S and molecular weight 241.27 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-((5H-[1,2,4]triazino[5,6-b]indol-3-yl)thio)acetonitrile (C11H7N5S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 241.27 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
