Chemical Structure
Description
The occurrence of 1-Hexadecyl-2-acetyl-sn-glycerol is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Hexadecyl-2-acetyl-sn-glycerol (CAS 77133-35-8), molecular formula C21H42O4 and molecular weight 358.56 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C21H42O4, 1-Hexadecyl-2-acetyl-sn-glycerol 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 358.56 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-Hexadecyl-2-acetyl-sn-glycerol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
