Chemical Structure

1-O-Octadecyl-rac-glycerol CAS 544-62-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-O-Octadecyl-rac-glycerol.

1-O-Octadecyl-rac-glycerol (CAS 544-62-7) is a high-purity analytical reference standard with the molecular formula C21H44O3 and a molecular weight of 344.57 g/mol.

The molecular framework of 1-O-Octadecyl-rac-glycerol (C21H44O3) is characterized by a carboxylic acid group, 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.

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

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.
