Chemical Structure
Description
The occurrence of 2-Bromo-5-bromomethyl-thiazole is closely related to a nitrile group, sulfur-containing functionality, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Bromo-5-bromomethyl-thiazole (CAS 131748-91-9) is a high-purity analytical reference standard with the molecular formula C4H3Br2NS and a molecular weight of 256.95 g/mol.
The molecular framework of 2-Bromo-5-bromomethyl-thiazole (C4H3Br2NS) is characterized by a nitrile group, sulfur-containing functionality, bromine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
