Chemical Structure
Description
CATO supplies tert-Butyl 4-hydroxy-2-oxo-2,5-dihydro-1H-pyrrole-1-carboxylate (CAS 182352-48-3), a certified reference material (molecular formula C9H13NO4, MW 199.20 g/mol) for analytical method development and quality control.
The molecular framework of tert-Butyl 4-hydroxy-2-oxo-2,5-dihydro-1H-pyrrole-1-carboxylate (C9H13NO4) 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. 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.
As a certified reference material (CRM), tert-Butyl 4-hydroxy-2-oxo-2,5-dihydro-1H-pyrrole-1-carboxylate 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.
