3227AE 4290-72-6 5,6-Dihydro-4H-pyrrolo[3,2,1-ij]quinoline-1,2-dione C11H9NO2 CAS 4290-72-6

Description

3227AE 4290-72-6 5,6-Dihydro-4H-pyrrolo[3,2,1-ij]quinoline-1,2-dione C11H9NO2 (CAS 4290-72-6), molecular formula C11H9NO2 and molecular weight 187.19 g/mol, is a CATO reference standard with documented purity and traceability.

3227AE 4290-72-6 5,6-Dihydro-4H-pyrrolo[3,2,1-ij]quinoline-1,2-dione C11H9NO2 (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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 manufactures 3227AE 4290-72-6 5,6-Dihydro-4H-pyrrolo[3,2,1-ij]quinoline-1,2-dione C11H9NO2 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
