8,8a-Dihydroindeno[1,2-c]pyrrole-1,3(2H,3aH)-dione CAS 4464-94-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 8,8a-Dihydroindeno[1,2-c]pyrrole-1,3(2H,3aH)-dione.

8,8a-Dihydroindeno[1,2-c]pyrrole-1,3(2H,3aH)-dione (CAS 4464-94-2), molecular formula C11H9NO2 and molecular weight 187.19 g/mol, is a CATO reference standard with documented purity and traceability.

8,8a-Dihydroindeno[1,2-c]pyrrole-1,3(2H,3aH)-dione (C11H9NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 8,8a-Dihydroindeno[1,2-c]pyrrole-1,3(2H,3aH)-dione 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.
