Chemical Structure
Description
Structurally, 2,3,5,6-Tetrachlorobiphenyl-2′,3′,4′,5′,6′-d5 (C12HD5Cl4) contains deuterium isotope labeling, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 10.5, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 297.02 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies 2,3,5,6-Tetrachlorobiphenyl-2′,3′,4′,5′,6′-d5 (CAS 1219794-80-5), a certified reference material (molecular formula C12HD5Cl4, MW 297.02 g/mol) for analytical method development and quality control.
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.
