2,3-Dibromobutane-1,4-diol CAS 20163-90-0 chemical structure

Description

As a certified reference material (CRM), 2,3-Dibromobutane-1,4-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.

2,3-Dibromobutane-1,4-diol (CAS 20163-90-0) is a high-purity analytical reference standard with the molecular formula C4H8Br2O2 and a molecular weight of 247.91 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, 2,3-Dibromobutane-1,4-diol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 247.91 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.
