Chemical Structure

1-Bromo-2-iodoethane CAS 590-16-9 chemical structure

Description

Owing to bromine/iodine substitution, 1-Bromo-2-iodoethane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 234.86 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.

1-Bromo-2-iodoethane (CAS 590-16-9), molecular formula C2H4BrI and molecular weight 234.86 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), 1-Bromo-2-iodoethane 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.
