The occurrence of 4-imino-2-mercapto-5-(4-methyl-1,3-thiazol-2-yl)-3-azaspiro[5.5]undec-1-ene-1-carbonitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-imino-2-mercapto-5-(4-methyl-1,3-thiazol-2-yl)-3-azaspiro[5.5]undec-1-ene-1-carbonitrile (CAS 851207-99-3) is a high-purity analytical reference standard with the molecular formula C15H18N4S2 and a molecular weight of 318.46 g/mol.
Based on its molecular formula C15H18N4S2, 4-imino-2-mercapto-5-(4-methyl-1,3-thiazol-2-yl)-3-azaspiro[5.5]undec-1-ene-1-carbonitrile contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 318.46 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
