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 6-(Tert-butyl)-2-((pyridin-4-ylmethyl)thio)-4-(thiophen-2-yl)-5,6,7,8-tetrahydroquinoline-3-carbonitrile.
6-(Tert-butyl)-2-((pyridin-4-ylmethyl)thio)-4-(thiophen-2-yl)-5,6,7,8-tetrahydroquinoline-3-carbonitrile (CAS 354556-51-7), molecular formula C24H25N3S2 and molecular weight 419.61 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 6-(Tert-butyl)-2-((pyridin-4-ylmethyl)thio)-4-(thiophen-2-yl)-5,6,7,8-tetrahydroquinoline-3-carbonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 419.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
