Chemical Structure
Description
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.
(2E,4E,6E,8E,10E)-4,9-Dimethyldodeca-2,4,6,8,10-pentaene-1,12-diol (CAS 53163-56-7) is a high-purity analytical reference standard with the molecular formula C14H20O2 and a molecular weight of 220.31 g/mol.
(2E,4E,6E,8E,10E)-4,9-Dimethyldodeca-2,4,6,8,10-pentaene-1,12-diol (C14H20O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), (2E,4E,6E,8E,10E)-4,9-Dimethyldodeca-2,4,6,8,10-pentaene-1,12-diol 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.
