Chemical Structure
Description
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.
2-(Methylthio)-N-(4-(5,6,7,8-tetrahydronaphthalen-2-yl)thiazol-2-yl)nicotinamide (CAS 568558-04-3), molecular formula C20H19N3OS2 and molecular weight 381.51 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(Methylthio)-N-(4-(5,6,7,8-tetrahydronaphthalen-2-yl)thiazol-2-yl)nicotinamide (C20H19N3OS2) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 381.51 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
