5-(6-((2-Fluorobenzyl)thio)pyridazin-3-yl)-2-(4-methoxyphenyl)-4-methylthiazole CAS 1040636-41-6

Description

Compared with other compounds in its class, the molecular weight of 423.53 g/mol gives 5-(6-((2-Fluorobenzyl)thio)pyridazin-3-yl)-2-(4-methoxyphenyl)-4-methylthiazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-(6-((2-Fluorobenzyl)thio)pyridazin-3-yl)-2-(4-methoxyphenyl)-4-methylthiazole (CAS 1040636-41-6), molecular formula C22H18FN3OS2 and molecular weight 423.53 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-(6-((2-Fluorobenzyl)thio)pyridazin-3-yl)-2-(4-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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
