Chemical Structure
Description
The occurrence of 4,4'-((2,2-Bis((4-aminophenoxy)methyl)propane-1,3-diyl)bis(oxy))dianiline is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4,4'-((2,2-Bis((4-aminophenoxy)methyl)propane-1,3-diyl)bis(oxy))dianiline (CAS 60713-81-7), a certified reference material (molecular formula C29H32N4O4, MW 500.59 g/mol) for analytical method development and quality control.
The molecular framework of 4,4'-((2,2-Bis((4-aminophenoxy)methyl)propane-1,3-diyl)bis(oxy))dianiline (C29H32N4O4) is characterized by a steroid core, an amide 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.
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.
