5-(6-((4-Fluorobenzyl)thio)pyridazin-3-yl)-2-(2-methoxyphenyl)-4-methylthiazole CAS 954661-87-1

Description

5-(6-((4-Fluorobenzyl)thio)pyridazin-3-yl)-2-(2-methoxyphenyl)-4-methylthiazole (CAS 954661-87-1) is a high-purity analytical reference standard with the molecular formula C22H18FN3OS2 and a molecular weight of 423.53 g/mol.

The molecular framework of 5-(6-((4-Fluorobenzyl)thio)pyridazin-3-yl)-2-(2-methoxyphenyl)-4-methylthiazole (C22H18FN3OS2) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
