Chemical Structure
Description
The occurrence of 6-(Bis(4-methoxyphenyl)(phenyl)methoxy)hexyl (2-cyanoethyl) diisopropylphosphoramidite is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 6-(Bis(4-methoxyphenyl)(phenyl)methoxy)hexyl (2-cyanoethyl) diisopropylphosphoramidite (CAS 158041-82-8), a certified reference material (molecular formula C36H49N2O5P, MW 620.76 g/mol) for analytical method development and quality control.
6-(Bis(4-methoxyphenyl)(phenyl)methoxy)hexyl (2-cyanoethyl) diisopropylphosphoramidite (C36H49N2O5P) contains a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
