4-Bromo-1,1,3,3,5,5,7,7-octaethyl-1,2,3,5,6,7-hexahydro-s-indacene CAS 960079-28-1

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.

4-Bromo-1,1,3,3,5,5,7,7-octaethyl-1,2,3,5,6,7-hexahydro-s-indacene (CAS 960079-28-1) is a high-purity analytical reference standard with the molecular formula C28H45Br and a molecular weight of 461.56 g/mol.

Owing to bromine substitution, an aromatic ring system, 4-Bromo-1,1,3,3,5,5,7,7-octaethyl-1,2,3,5,6,7-hexahydro-s-indacene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 461.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
