Description

156856-30-3 5,5-Dihydro-5-methyl-6-(1,5-dimethyl-6-hydroxy-4-(phosphoryloxy)trideca-7,9,11-trienyl)-2H-pyran-2-one (sodium salt) sodium (8Z,10Z,12E)-7-hydroxy-6-methyl-2-(3-methyl-6-oxo-3,6-dihydro-2H-pyran-2-yl)tetradeca-8,10,12-trien-5-yl hydrogenphosphate (CAS 156856-30-3) is a high-purity analytical reference standard with the molecular formula C21H32O7PNa and a molecular weight of 450.44 g/mol.

Structurally, 156856-30-3 5,5-Dihydro-5-methyl-6-(1,5-dimethyl-6-hydroxy-4-(phosphoryloxy)trideca-7,9,11-trienyl)-2H-pyran-2-one (sodium salt) sodium (8Z,10Z,12E)-7-hydroxy-6-methyl-2-(3-methyl-6-oxo-3,6-dihydro-2H-pyran-2-yl)tetradeca-8,10,12-trien-5-yl hydrogenphosphate (C21H32O7PNa) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 450.44 g/mol, it falls into the moderately-high-molecular-weight range. 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), 156856-30-3 5,5-Dihydro-5-methyl-6-(1,5-dimethyl-6-hydroxy-4-(phosphoryloxy)trideca-7,9,11-trienyl)-2H-pyran-2-one (sodium salt) sodium (8Z,10Z,12E)-7-hydroxy-6-methyl-2-(3-methyl-6-oxo-3,6-dihydro-2H-pyran-2-yl)tetradeca-8,10,12-trien-5-yl hydrogenphosphate 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.
