Chemical Structure
Description
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.
CATO supplies (E)-({4-[(6-chloropyridin-3-yl)methoxy]-3-methoxyphenyl}methylidene)[(oxolan-2-yl)methyl]amine (CAS 861207-82-1), a certified reference material (molecular formula C19H21ClN2O3, MW 360.83 g/mol) for analytical method development and quality control.
(E)-({4-[(6-chloropyridin-3-yl)methoxy]-3-methoxyphenyl}methylidene)[(oxolan-2-yl)methyl]amine (C19H21ClN2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
