Chemical Structure
Description
Based on its molecular formula C20H40O4, Polyethylene glycol 12-hydroxystearate contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 344.53 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Polyethylene glycol 12-hydroxystearate (CAS 61909-81-7) is a high-purity analytical reference standard with the molecular formula C20H40O4 and a molecular weight of 344.53 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
