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 4-(Methoxycarbonyl)-5-(pyrrolidine-1-carbonyl)furan-3-carboxylic acid (CAS 50347-44-9), a certified reference material (molecular formula C12H13NO6, MW 267.23 g/mol) for analytical method development and quality control.
The molecular framework of 4-(Methoxycarbonyl)-5-(pyrrolidine-1-carbonyl)furan-3-carboxylic acid (C12H13NO6) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), 4-(Methoxycarbonyl)-5-(pyrrolidine-1-carbonyl)furan-3-carboxylic 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.
