1,2-Dielaidoyl-sn-glycero-3-phosphocholine 56782-46-8 L-|A-Phosphatidylcholine, dielaidoyl CAS 56782-46-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 786.11 g/mol gives 1,2-Dielaidoyl-sn-glycero-3-phosphocholine 56782-46-8 L-|A-Phosphatidylcholine, dielaidoyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,2-Dielaidoyl-sn-glycero-3-phosphocholine 56782-46-8 L-|A-Phosphatidylcholine, dielaidoyl (CAS 56782-46-8), molecular formula C44H84NO8P and molecular weight 786.11 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,2-Dielaidoyl-sn-glycero-3-phosphocholine 56782-46-8 L-|A-Phosphatidylcholine, dielaidoyl (C44H84NO8P) 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 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 786.11 g/mol, it falls into the high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
