Chemical Structure
Description
The occurrence of 2,5-Dichlorothiazole is closely related to a nitrile group, sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,5-Dichlorothiazole (CAS 16629-14-4), a certified reference material (molecular formula C3HCl2NS, MW 154.02 g/mol) for analytical method development and quality control.
Based on its molecular formula C3HCl2NS, 2,5-Dichlorothiazole contains a nitrile group, sulfur-containing functionality, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 154.02 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
