Chemical Structure
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 1346604-31-6 2,2'-(4-Bromo-1-butenylidene)bis-3-methyl-d6-thiophene (CAS 1346604-31-6), a certified reference material (molecular formula C14H9D6BrS2, MW 333.34 g/mol) for analytical method development and quality control.
1346604-31-6 2,2'-(4-Bromo-1-butenylidene)bis-3-methyl-d6-thiophene (C14H9D6BrS2) contains deuterium isotope labeling, sulfur-containing functionality, bromine substitution, a polycyclic aromatic system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
