Bromoethane-2-<SUP>13</SUP>C CAS 117890-45-6

Description

Compared with other compounds in its class, the molecular weight of 109.96 g/mol gives Bromoethane-2-<SUP>13</SUP>C distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Bromoethane-2-<SUP>13</SUP>C (CAS 117890-45-6), a certified reference material (molecular formula C[13C]H5Br, MW 109.96 g/mol) for analytical method development and quality control.

Owing to bromine substitution, Bromoethane-2-<SUP>13</SUP>C is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 109.96 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
