Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (+/-)-1-(1,2-Diphenylethyl)piperidine maleate.
CATO supplies (+/-)-1-(1,2-Diphenylethyl)piperidine maleate (CAS 207461-99-2), a certified reference material (molecular formula C19H23NC4H4O4, MW 381.47 g/mol) for analytical method development and quality control.
(+/-)-1-(1,2-Diphenylethyl)piperidine maleate (C19H23NC4H4O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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.
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.
