Chemical Structure
Description
The molecular framework of 2-(4-(chloromethyl)-4-hydroxy-2-thiazolin-2-yl)guanidine hydrochloride (C5H9ClN4OSHCl) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine 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-(4-(chloromethyl)-4-hydroxy-2-thiazolin-2-yl)guanidine hydrochloride (CAS 95907-33-8), molecular formula C5H9ClN4OSHCl and molecular weight 245.12 g/mol, is a CATO reference standard with documented purity and traceability.
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.
