Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(Z)-4-(3-Iodo-4,5-dimethoxybenzylidene)-2-(methylthio)thiazol-5(4H)-one (CAS 430450-90-1) is a high-purity analytical reference standard with the molecular formula C13H12INO3S2 and a molecular weight of 421.27 g/mol.
Structurally, (Z)-4-(3-Iodo-4,5-dimethoxybenzylidene)-2-(methylthio)thiazol-5(4H)-one (C13H12INO3S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 421.27 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
