Chemical Structure

5,5-Bis(bromomethyl)-2,2-dimethyl-1,3-dioxane CAS 43153-20-4 chemical structure

Description

5,5-Bis(bromomethyl)-2,2-dimethyl-1,3-dioxane (CAS 43153-20-4), molecular formula C8H14Br2O2 and molecular weight 302.00 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, 5,5-Bis(bromomethyl)-2,2-dimethyl-1,3-dioxane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 302.00 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), 5,5-Bis(bromomethyl)-2,2-dimethyl-1,3-dioxane 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.
