Chemical Structure
Description
The occurrence of C18:1 1-Phosphoceramide (d18:1/18:1(9Z)) is closely related to an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
C18:1 1-Phosphoceramide (d18:1/18:1(9Z)) (CAS 1246304-33-5), molecular formula C36H69NO6PH4N and molecular weight 660.96 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C36H69NO6PH4N, C18:1 1-Phosphoceramide (d18:1/18:1(9Z)) contains an amide group, a phosphate ester group, 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 660.96 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
