1,2-Dibromo-1-chloro-2,2-difluoroethane CAS 421-36-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,2-Dibromo-1-chloro-2,2-difluoroethane.

1,2-Dibromo-1-chloro-2,2-difluoroethane (CAS 421-36-3) is a high-purity analytical reference standard with the molecular formula C2HBr2ClF2 and a molecular weight of 258.29 g/mol.

Structurally, 1,2-Dibromo-1-chloro-2,2-difluoroethane (C2HBr2ClF2) contains fluorine/chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 258.29 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.

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.
