Chemical Structure

1-Bromooctadecane-18,18,18-d3 CAS 349553-85-1 chemical structure

Description

1-Bromooctadecane-18,18,18-d3 (CAS 349553-85-1), molecular formula C18H34D3Br and molecular weight 336.41 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C18H34D3Br, 1-Bromooctadecane-18,18,18-d3 contains deuterium isotope labeling, bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 336.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
