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.
2-(Diphenylphosphino)-N-(1H-pyrrol-2-ylmethylene)benzenamine (CAS 649749-98-4) is a high-purity analytical reference standard with the molecular formula C23H19N2P and a molecular weight of 354.38 g/mol.
Structurally, 2-(Diphenylphosphino)-N-(1H-pyrrol-2-ylmethylene)benzenamine (C23H19N2P) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, organophosphorus functionality. The molecule exhibits a degree of unsaturation (DBE) of 15.5, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 354.38 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
