1-Bromo-4-[chloro(difluoro)methoxy]-2,3-difluoro-benzene CAS 1417567-60-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-Bromo-4-[chloro(difluoro)methoxy]-2,3-difluoro-benzene.

1-Bromo-4-[chloro(difluoro)methoxy]-2,3-difluoro-benzene (CAS 1417567-60-2), molecular formula C7H2BrClF4O and molecular weight 293.44 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-Bromo-4-[chloro(difluoro)methoxy]-2,3-difluoro-benzene (C7H2BrClF4O) 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 293.44 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.

As a certified reference material (CRM), 1-Bromo-4-[chloro(difluoro)methoxy]-2,3-difluoro-benzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
