1-stearoyl-2-linoleoyl-sn-glycero-3-phosphoethanolamine 7266-53-7 CAS 7266-53-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 744.03 g/mol gives 1-stearoyl-2-linoleoyl-sn-glycero-3-phosphoethanolamine 7266-53-7 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-stearoyl-2-linoleoyl-sn-glycero-3-phosphoethanolamine 7266-53-7 (CAS 7266-53-7), molecular formula C41H78NO8P and molecular weight 744.03 g/mol, is a CATO reference standard with documented purity and traceability.

1-stearoyl-2-linoleoyl-sn-glycero-3-phosphoethanolamine 7266-53-7 (C41H78NO8P) contains an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
