2-Bromoethanol CAS 540-51-2 chemical structure

Description

2-Bromoethanol (CAS 540-51-2) is a high-purity analytical reference standard with the molecular formula C2H5BrO and a molecular weight of 124.96 g/mol.

Structurally, 2-Bromoethanol (C2H5BrO) contains a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 124.96 g/mol, it falls into the low-molecular-weight range. 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), 2-Bromoethanol 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.
