Description

1-Octadecanoyl-2-(cis-9-Octadecenoyl)-sn-glycero-3-phosphocholine 2-Oleoyl-1-stearoyl-sn-glycero-3-phosphocholine 56421-10-4 L-|A-Phosphatidylcholine, |A-oleoyl-|A-stearoyl (CAS 56421-10-4), molecular formula C44H86NO8P and molecular weight 788.13 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-Octadecanoyl-2-(cis-9-Octadecenoyl)-sn-glycero-3-phosphocholine 2-Oleoyl-1-stearoyl-sn-glycero-3-phosphocholine 56421-10-4 L-|A-Phosphatidylcholine, |A-oleoyl-|A-stearoyl (C44H86NO8P) contains an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.5, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 788.13 g/mol, it falls into the high-molecular-weight range. 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.
