Chemical Structure

1-Bromo-3,6-di-tert-butylnaphthalene CAS 10239-76-6 chemical structure

Description

The occurrence of 1-Bromo-3,6-di-tert-butylnaphthalene is closely related to bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-Bromo-3,6-di-tert-butylnaphthalene (CAS 10239-76-6), a certified reference material (molecular formula C18H23Br, MW 319.28 g/mol) for analytical method development and quality control.

Based on its molecular formula C18H23Br, 1-Bromo-3,6-di-tert-butylnaphthalene contains bromine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 319.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
