Chemical Structure

4-Bromobutane-1,2-diol CAS 33835-83-5 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, 4-Bromobutane-1,2-diol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 169.02 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.

4-Bromobutane-1,2-diol (CAS 33835-83-5), molecular formula C4H9BrO2 and molecular weight 169.02 g/mol, is a CATO reference standard with documented purity and traceability.

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), 4-Bromobutane-1,2-diol 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.
