Chemical Structure
Description
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.
4542-77-2 2,6-Bis(bromomethyl)naphthalene DTXSID70394761 (CAS 4542-77-2), molecular formula C12H20Br2 and molecular weight 324.10 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H20Br2, 4542-77-2 2,6-Bis(bromomethyl)naphthalene DTXSID70394761 contains bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 324.10 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.
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.
