Chemical Structure
Description
The occurrence of Hexachloro-1,3-butadiene-13C4 is closely related to chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Hexachloro-1,3-butadiene-13C4 (CAS 93951-70-3), a certified reference material (molecular formula [13C]4Cl6, MW 264.73 g/mol) for analytical method development and quality control.
Owing to chlorine substitution, Hexachloro-1,3-butadiene-13C4 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 264.73 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
