(R)-1-Methyl-4-(6-methylhept-5-en-2-yl)cyclohexa-1,3-diene CAS 28976-68-3 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 (R)-1-Methyl-4-(6-methylhept-5-en-2-yl)cyclohexa-1,3-diene (CAS 28976-68-3), a certified reference material (molecular formula C15H24, MW 204.35 g/mol) for analytical method development and quality control.

Owing to an aromatic ring system, (R)-1-Methyl-4-(6-methylhept-5-en-2-yl)cyclohexa-1,3-diene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 204.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
