Chemical Structure

(Z)-1-Bromo-6,6-dimethylhept-2-en-4-yne CAS 78629-19-3 chemical structure

Description

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.

CATO supplies (Z)-1-Bromo-6,6-dimethylhept-2-en-4-yne (CAS 78629-19-3), a certified reference material (molecular formula C9H13Br, MW 201.10 g/mol) for analytical method development and quality control.

Structurally, (Z)-1-Bromo-6,6-dimethylhept-2-en-4-yne (C9H13Br) contains bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 201.10 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
