Chemical Structure
Description
The occurrence of 4-Bromo-2-(methoxy-d3)thiazole is closely related to deuterium isotope labeling, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Bromo-2-(methoxy-d3)thiazole (CAS 1185311-79-8), molecular formula C4HD3BrNOS and molecular weight 197.07 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-Bromo-2-(methoxy-d3)thiazole (C4HD3BrNOS) contains deuterium isotope labeling, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 197.07 g/mol, it falls into the medium-molecular-weight range. 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.
As a certified reference material (CRM), 4-Bromo-2-(methoxy-d3)thiazole 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.
