Chemical Structure
Description
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.
4-(2-(Diphenylphosphino)naphthalen-1-yl)-2-isopropylquinazoline (CAS 787638-36-2) is a high-purity analytical reference standard with the molecular formula C33H27N2P and a molecular weight of 482.55 g/mol.
Based on its molecular formula C33H27N2P, 4-(2-(Diphenylphosphino)naphthalen-1-yl)-2-isopropylquinazoline contains a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 482.55 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
