Chemical Structure

4,5-Dimethylnonane CAS 17302-23-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 4,5-Dimethylnonane (CAS 17302-23-7), a certified reference material (molecular formula C23H20, MW 296.40 g/mol) for analytical method development and quality control.

Owing to a polycyclic aromatic system, 4,5-Dimethylnonane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 296.40 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.
