Chemical Structure
Description
The molecular framework of Phosphoric acid, diethyl ester, compd. with N,N-diethylethanamine (1:1) (C4H11O4PC6H15N) is characterized by an amide group, a phosphate ester 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.
Phosphoric acid, diethyl ester, compd. with N,N-diethylethanamine (1:1) (CAS 5802-76-6) is a high-purity analytical reference standard with the molecular formula C4H11O4PC6H15N and a molecular weight of 255.29 g/mol.
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.
