Chemical Structure
Description
The occurrence of Di(pyrrolidin-1-yl)phosphinic anhydride is closely related to an amide group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Di(pyrrolidin-1-yl)phosphinic anhydride (CAS 51833-62-6) is a high-purity analytical reference standard with the molecular formula C16H32N4O3P2 and a molecular weight of 390.40 g/mol.
The molecular framework of Di(pyrrolidin-1-yl)phosphinic anhydride (C16H32N4O3P2) is characterized by an amide group, a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
