1,2-Dibromo-3,5-dichlorobenzene CAS 81067-40-5

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-3,5-dichlorobenzene.

1,2-Dibromo-3,5-dichlorobenzene (CAS 81067-40-5) is a high-purity analytical reference standard with the molecular formula C6H2Br2Cl2 and a molecular weight of 304.79 g/mol.

Owing to chlorine/bromine substitution, an aromatic ring system, 1,2-Dibromo-3,5-dichlorobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.79 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 1,2-Dibromo-3,5-dichlorobenzene 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.
