Chemical Structure

(7R,11R)-3,7,11,15-Tetramethylhexadecan-3-ol CAS 20685-73-8 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 (7R,11R)-3,7,11,15-Tetramethylhexadecan-3-ol (CAS 20685-73-8), a certified reference material (molecular formula C20H42O, MW 298.55 g/mol) for analytical method development and quality control.

The molecular framework of (7R,11R)-3,7,11,15-Tetramethylhexadecan-3-ol (C20H42O) is characterized by a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
