Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 5-Methyl-2-[(1-phenyl-2-pyrrolidinylidene)amino]benzoic Acid Methyl Ester 856925-73-0 Methyl 5-Methyl-2-[(1-phenylpyrrolidene)amino]benzoate (CAS 856925-73-0), a certified reference material (molecular formula C19H20N2O2, MW 308.37 g/mol) for analytical method development and quality control.
The molecular framework of 5-Methyl-2-[(1-phenyl-2-pyrrolidinylidene)amino]benzoic Acid Methyl Ester 856925-73-0 Methyl 5-Methyl-2-[(1-phenylpyrrolidene)amino]benzoate (C19H20N2O2) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 5-Methyl-2-[(1-phenyl-2-pyrrolidinylidene)amino]benzoic Acid Methyl Ester 856925-73-0 Methyl 5-Methyl-2-[(1-phenylpyrrolidene)amino]benzoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
