Chemical Structure
Description
3-Oxo-5-phenyl-2,3-dihydro-1H-pyrrolo[2,1-a]isoindole-1-carboxylic acid (CAS 88894-22-8), molecular formula C18H13NO3 and molecular weight 291.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Oxo-5-phenyl-2,3-dihydro-1H-pyrrolo[2,1-a]isoindole-1-carboxylic acid (C18H13NO3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-Oxo-5-phenyl-2,3-dihydro-1H-pyrrolo[2,1-a]isoindole-1-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.
