5-(6-Chloropyridazin-3-yl)-3-(thiophen-2-ylmethyl)-1,2,4-thiadiazole CAS 930002-18-9

Description

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.

CATO supplies 5-(6-Chloropyridazin-3-yl)-3-(thiophen-2-ylmethyl)-1,2,4-thiadiazole (CAS 930002-18-9), a certified reference material (molecular formula C11H7ClN4S2, MW 294.78 g/mol) for analytical method development and quality control.

5-(6-Chloropyridazin-3-yl)-3-(thiophen-2-ylmethyl)-1,2,4-thiadiazole (C11H7ClN4S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
