Chemical Structure
Description
The molecular framework of 2-Iodothiazole-5-carboxylic acid (C4H2INO2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
2-Iodothiazole-5-carboxylic acid (CAS 2090961-67-2) is a high-purity analytical reference standard with the molecular formula C4H2INO2S and a molecular weight of 255.03 g/mol.
