Description

As a certified reference material (CRM), 8-Methoxy-4,4,6-trimethyl-5,6-dihydro-4H-pyrrolo-[3,2,1-ij]quinoline-1,2-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.

8-Methoxy-4,4,6-trimethyl-5,6-dihydro-4H-pyrrolo-[3,2,1-ij]quinoline-1,2-dione (CAS 443321-74-2), molecular formula C15H17NO3 and molecular weight 259.30 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 8-Methoxy-4,4,6-trimethyl-5,6-dihydro-4H-pyrrolo-[3,2,1-ij]quinoline-1,2-dione (C15H17NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 259.30 g/mol, it falls into the medium-molecular-weight range. 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.
