Chemical Structure
Description
(Z)-1-Bromo-3,7-dimethylocta-2,6-diene (CAS 25996-10-5), molecular formula C10H17Br and molecular weight 217.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to bromine substitution, (Z)-1-Bromo-3,7-dimethylocta-2,6-diene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 217.15 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.
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.
