1,4-Bis(brommethyl)-2,5-dichlorobenzene CAS 19036-27-2 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

1,4-Bis(brommethyl)-2,5-dichlorobenzene (CAS 19036-27-2), molecular formula C8H6Br2Cl2 and molecular weight 332.85 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to chlorine/bromine substitution, an aromatic ring system, 1,4-Bis(brommethyl)-2,5-dichlorobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 332.85 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.

As a certified reference material (CRM), 1,4-Bis(brommethyl)-2,5-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.
