Tetrabromobisphenol A Bis(2,3-dibromopropyl) Ether CAS 21850-44-2

Description

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.

Tetrabromobisphenol A Bis(2,3-dibromopropyl) Ether (CAS 21850-44-2) is a high-purity analytical reference standard with the molecular formula C21H20Br8O2 and a molecular weight of 943.61 g/mol.

Owing to a steroid core, a hydroxyl group, an ether linkage, bromine substitution, Tetrabromobisphenol A Bis(2,3-dibromopropyl) Ether is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 943.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

As a certified reference material (CRM), Tetrabromobisphenol A Bis(2,3-dibromopropyl) Ether 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.
