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.
4-(((2H-Pyrrol-2-ylidene)methyl)amino)benzoic acid (CAS 80525-79-7), molecular formula C12H10N2O2 and molecular weight 214.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(((2H-Pyrrol-2-ylidene)methyl)amino)benzoic acid (C12H10N2O2) is characterized by an amino-acid-derived structure, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), 4-(((2H-Pyrrol-2-ylidene)methyl)amino)benzoic acid 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.
