4,4'-Bis(5'-(hexylthio)-[2,2'-bithiophen]-5-yl)-2,2'-bipyridine CAS 1190631-38-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,4'-Bis(5'-(hexylthio)-[2,2'-bithiophen]-5-yl)-2,2'-bipyridine.

4,4'-Bis(5'-(hexylthio)-[2,2'-bithiophen]-5-yl)-2,2'-bipyridine (CAS 1190631-38-9) is a high-purity analytical reference standard with the molecular formula C38H40N2S6 and a molecular weight of 717.13 g/mol.

Structurally, 4,4'-Bis(5'-(hexylthio)-[2,2'-bithiophen]-5-yl)-2,2'-bipyridine (C38H40N2S6) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 20.0, corresponding to approximately 20 ring(s) or double-bond equivalent(s). With a molecular weight of 717.13 g/mol, it falls into the 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.
