Chemical Structure
Description
As a certified reference material (CRM), 5-(6-((4-Bromobenzyl)thio)pyridazin-3-yl)-2-(4-methoxyphenyl)-4-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.
5-(6-((4-Bromobenzyl)thio)pyridazin-3-yl)-2-(4-methoxyphenyl)-4-methylthiazole (CAS 954661-79-1), molecular formula C22H18BrN3OS2 and molecular weight 484.43 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(6-((4-Bromobenzyl)thio)pyridazin-3-yl)-2-(4-methoxyphenyl)-4-methylthiazole (C22H18BrN3OS2) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
