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 5-[(E)-2-(Dimethylamino)ethenyl]-3-{[(2-methyl-1,3-thiazol-4-yl)methyl]sulfanyl}-1,2-thiazole-4-carbonitrile.
5-[(E)-2-(Dimethylamino)ethenyl]-3-{[(2-methyl-1,3-thiazol-4-yl)methyl]sulfanyl}-1,2-thiazole-4-carbonitrile (CAS 338778-83-9) is a high-purity analytical reference standard with the molecular formula C13H14N4S3 and a molecular weight of 322.47 g/mol.
5-[(E)-2-(Dimethylamino)ethenyl]-3-{[(2-methyl-1,3-thiazol-4-yl)methyl]sulfanyl}-1,2-thiazole-4-carbonitrile (C13H14N4S3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
