6-((2-Methylbenzyl)thio)-3-(pyridin-4-yl)-[1,2,4]triazolo[4,3-b]pyridazine CAS 868970-19-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-((2-Methylbenzyl)thio)-3-(pyridin-4-yl)-[1,2,4]triazolo[4,3-b]pyridazine.

6-((2-Methylbenzyl)thio)-3-(pyridin-4-yl)-[1,2,4]triazolo[4,3-b]pyridazine (CAS 868970-19-8) is a high-purity analytical reference standard with the molecular formula C18H15N5S and a molecular weight of 333.41 g/mol.

Structurally, 6-((2-Methylbenzyl)thio)-3-(pyridin-4-yl)-[1,2,4]triazolo[4,3-b]pyridazine (C18H15N5S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 333.41 g/mol, it falls into the moderately-high-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.
