Description
As a certified reference material (CRM), 1-octadecanoyl-2-(9Z,12Z-octadecadienoyl)-sn-glycero-3-phosphate (sodium salt) 1-stearoyl-2-linoleoyl-sn-glycero-3-phosphate (sodium salt) 18:0-18:2 PA 474943-29-8 PA(18:0/18:2(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.
CATO supplies 1-octadecanoyl-2-(9Z,12Z-octadecadienoyl)-sn-glycero-3-phosphate (sodium salt) 1-stearoyl-2-linoleoyl-sn-glycero-3-phosphate (sodium salt) 18:0-18:2 PA 474943-29-8 PA(18:0/18:2(9Z,12Z)) (CAS 474943-29-8), a certified reference material (molecular formula C39H72O8PNa, MW 722.96 g/mol) for analytical method development and quality control.
Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 1-octadecanoyl-2-(9Z,12Z-octadecadienoyl)-sn-glycero-3-phosphate (sodium salt) 1-stearoyl-2-linoleoyl-sn-glycero-3-phosphate (sodium salt) 18:0-18:2 PA 474943-29-8 PA(18:0/18:2(9Z,12Z)) is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 722.96 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
