Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,2-di-(9Z,12Z-octadecadienoyl)-sn-glycero-3-phospho-L-serine (sodium salt) 383907-33-3 L-alpha-Phosphatidylinositol(Liver, Bovine-Sodium Salt) Liver PI PS(18:2(9Z,12Z)/18:2(9Z,12Z)).
1,2-di-(9Z,12Z-octadecadienoyl)-sn-glycero-3-phospho-L-serine (sodium salt) 383907-33-3 L-alpha-Phosphatidylinositol(Liver, Bovine-Sodium Salt) Liver PI PS(18:2(9Z,12Z)/18:2(9Z,12Z)) (CAS 383907-33-3), molecular formula C47H82O13PNa and molecular weight 909.12 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,2-di-(9Z,12Z-octadecadienoyl)-sn-glycero-3-phospho-L-serine (sodium salt) 383907-33-3 L-alpha-Phosphatidylinositol(Liver, Bovine-Sodium Salt) Liver PI PS(18:2(9Z,12Z)/18:2(9Z,12Z)) (C47H82O13PNa) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), 1,2-di-(9Z,12Z-octadecadienoyl)-sn-glycero-3-phospho-L-serine (sodium salt) 383907-33-3 L-alpha-Phosphatidylinositol(Liver, Bovine-Sodium Salt) Liver PI PS(18:2(9Z,12Z)/18:2(9Z,12Z)) 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.
