2,6,10,14,18-Pentamethylnonadecane CAS 55191-61-2 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.

2,6,10,14,18-Pentamethylnonadecane (CAS 55191-61-2) is a high-purity analytical reference standard with the molecular formula C24H50 and a molecular weight of 338.65 g/mol.

Owing to an organic framework, 2,6,10,14,18-Pentamethylnonadecane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 338.65 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.
