Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 213843-90-4 (3aR,8aR)-N,N,2,2-Tetramethyl-4,4,8,8-tetraphenyltetrahydro-2H,6H-[1,3]dioxolo[4,5-e][1,3,2]dioxaphosphepin-6-amine DTXSID40456805.
213843-90-4 (3aR,8aR)-N,N,2,2-Tetramethyl-4,4,8,8-tetraphenyltetrahydro-2H,6H-[1,3]dioxolo[4,5-e][1,3,2]dioxaphosphepin-6-amine DTXSID40456805 (CAS 213843-90-4), molecular formula C33H58NO4P and molecular weight 563.79 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 213843-90-4 (3aR,8aR)-N,N,2,2-Tetramethyl-4,4,8,8-tetraphenyltetrahydro-2H,6H-[1,3]dioxolo[4,5-e][1,3,2]dioxaphosphepin-6-amine DTXSID40456805 (C33H58NO4P) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
