Chemical Structure

1,2,4,5-Tetrachlorobenzene-d2 CAS 1198-57-8 chemical structure

Description

1,2,4,5-Tetrachlorobenzene-d2 (CAS 1198-57-8) is a high-purity analytical reference standard with the molecular formula C6D2Cl4 and a molecular weight of 217.90 g/mol.

1,2,4,5-Tetrachlorobenzene-d2 (C6D2Cl4) contains deuterium isotope labeling, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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.

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.
