12P 3,6,9,12,15,18,21,24,27,30,33-Undecaoxapentatriacontane-1,35-diol (9CI) 6790-09-6 DODECAETHYLENE GLYCOL Dodecaethylene glycol (7CI,8CI) PED-diol (n=12) POLYETHYLENE GLYCOL PEG400 (CAS 6790-09-6) is a high-purity analytical reference standard with the molecular formula C24H50O13 and a molecular weight of 546.65 g/mol.
The molecular framework of 12P 3,6,9,12,15,18,21,24,27,30,33-Undecaoxapentatriacontane-1,35-diol (9CI) 6790-09-6 DODECAETHYLENE GLYCOL Dodecaethylene glycol (7CI,8CI) PED-diol (n=12) POLYETHYLENE GLYCOL PEG400 (C24H50O13) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
As a certified reference material (CRM), 12P 3,6,9,12,15,18,21,24,27,30,33-Undecaoxapentatriacontane-1,35-diol (9CI) 6790-09-6 DODECAETHYLENE GLYCOL Dodecaethylene glycol (7CI,8CI) PED-diol (n=12) POLYETHYLENE GLYCOL PEG400 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.
