Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 283.16 g/mol gives 3-Bromo-1,9-dihydropyrene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Bromo-1,9-dihydropyrene (CAS 1956377-64-2), a certified reference material (molecular formula C16H11Br, MW 283.16 g/mol) for analytical method development and quality control.
Structurally, 3-Bromo-1,9-dihydropyrene (C16H11Br) contains bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 283.16 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
