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.
6-Methyl-2-((2-methylbenzyl)thio)-4-(thiophen-2-yl)-5,6,7,8-tetrahydro-1,6-naphthyridine-3-carbonitrile (CAS 445383-70-0), molecular formula C22H21N3S2 and molecular weight 391.55 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-Methyl-2-((2-methylbenzyl)thio)-4-(thiophen-2-yl)-5,6,7,8-tetrahydro-1,6-naphthyridine-3-carbonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 391.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
