Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 290.30 g/mol gives 4-(Diphenylphosphino)benzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-(Diphenylphosphino)benzaldehyde (CAS 5068-18-8) is a high-purity analytical reference standard with the molecular formula C19H15OP and a molecular weight of 290.30 g/mol.
Structurally, 4-(Diphenylphosphino)benzaldehyde (C19H15OP) contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.5, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 290.30 g/mol, it falls into the medium-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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
