Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 344.47 g/mol gives Dihydroxy(stearoyloxy)aluminum distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dihydroxy(stearoyloxy)aluminum (CAS 7047-84-9) is a high-purity analytical reference standard with the molecular formula C18H37AlO4 and a molecular weight of 344.47 g/mol.
Structurally, Dihydroxy(stearoyloxy)aluminum (C18H37AlO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 344.47 g/mol, it falls into the moderately-high-molecular-weight range. 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.
CATO manufactures Dihydroxy(stearoyloxy)aluminum under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
