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 Methyl 2-((4-phenylpiperazin-1-yl)methyl)-3-(3-phenylureido)benzoate.
CATO supplies Methyl 2-((4-phenylpiperazin-1-yl)methyl)-3-(3-phenylureido)benzoate (CAS 865660-28-2), a certified reference material (molecular formula C26H28N4O3, MW 444.53 g/mol) for analytical method development and quality control.
Methyl 2-((4-phenylpiperazin-1-yl)methyl)-3-(3-phenylureido)benzoate (C26H28N4O3) contains a steroid core, an amide 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.
