Chemical Structure
Description
2-Iodo-5-methylthiazole (CAS 847547-16-4) is a high-purity analytical reference standard with the molecular formula C4H4INS and a molecular weight of 225.05 g/mol.
Structurally, 2-Iodo-5-methylthiazole (C4H4INS) contains a nitrile group, sulfur-containing functionality, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 225.05 g/mol, it falls into the medium-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.
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.
As a certified reference material (CRM), 2-Iodo-5-methylthiazole meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
