Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 344.49 g/mol gives (3Z,6E,8E,12Z,15Z,18Z)-Docosa-3,6,8,12,15,18-hexaen-10-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (3Z,6E,8E,12Z,15Z,18Z)-Docosa-3,6,8,12,15,18-hexaen-10-ol (CAS 90780-53-3), a certified reference material (molecular formula C22H32O3, MW 344.49 g/mol) for analytical method development and quality control.
Based on its molecular formula C22H32O3, (3Z,6E,8E,12Z,15Z,18Z)-Docosa-3,6,8,12,15,18-hexaen-10-ol contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 344.49 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
