Chemical Structure

72802-81-4 Bromoform-13C Tribromomethane-13C CAS 72802-81-4 chemical structure

Description

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.

72802-81-4 Bromoform-13C Tribromomethane-13C (CAS 72802-81-4) is a high-purity analytical reference standard with the molecular formula [13C]HBr3 and a molecular weight of 253.72 g/mol.

72802-81-4 Bromoform-13C Tribromomethane-13C ([13C]HBr3) contains bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
