Chemical Structure

(3R,7R,11R)-3,7,11,15-Tetramethylhexadecan-1-ol CAS 18654-63-2 chemical structure

Description

Structurally, (3R,7R,11R)-3,7,11,15-Tetramethylhexadecan-1-ol (C20H42O) contains a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 298.55 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

(3R,7R,11R)-3,7,11,15-Tetramethylhexadecan-1-ol (CAS 18654-63-2), molecular formula C20H42O and molecular weight 298.55 g/mol, is a CATO reference standard with documented purity and traceability.

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.
