2,4-Dichloro-6-(difluoromethoxy)benzyl bromide CAS 1806350-55-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,4-Dichloro-6-(difluoromethoxy)benzyl bromide.

2,4-Dichloro-6-(difluoromethoxy)benzyl bromide (CAS 1806350-55-9) is a high-purity analytical reference standard with the molecular formula C8H5BrCl2F2O and a molecular weight of 305.93 g/mol.

Structurally, 2,4-Dichloro-6-(difluoromethoxy)benzyl bromide (C8H5BrCl2F2O) contains a hydroxyl group, an ether linkage, fluorine/chlorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 305.93 g/mol, it falls into the moderately-high-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.
