Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 797.04 g/mol gives 1,2-di-(9E-octadecenoyl)-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 1,2-dielaidoyl-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 18:1 (?9-Trans) PG 322647-40-5 PG(18:1(9E)/18:1(9E)) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1,2-di-(9E-octadecenoyl)-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 1,2-dielaidoyl-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 18:1 (?9-Trans) PG 322647-40-5 PG(18:1(9E)/18:1(9E)) (CAS 322647-40-5), a certified reference material (molecular formula C42H78O10PNa, MW 797.04 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, 1,2-di-(9E-octadecenoyl)-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 1,2-dielaidoyl-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 18:1 (?9-Trans) PG 322647-40-5 PG(18:1(9E)/18:1(9E)) is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 797.04 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 1,2-di-(9E-octadecenoyl)-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 1,2-dielaidoyl-sn-glycero-3-phospho-(1'-rac-glycerol) (sodium salt) 18:1 (?9-Trans) PG 322647-40-5 PG(18:1(9E)/18:1(9E)) meets the metrological traceability requirements of ISO/IEC 17025 laboratories.
