Chemical Structure

(E)-1-Bromo-6,6-dimethylhept-2-en-4-yne CAS 78629-21-7 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.

CATO supplies (E)-1-Bromo-6,6-dimethylhept-2-en-4-yne (CAS 78629-21-7), a certified reference material (molecular formula C9H13Br, MW 201.10 g/mol) for analytical method development and quality control.

Owing to bromine substitution, (E)-1-Bromo-6,6-dimethylhept-2-en-4-yne is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 201.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
