2H-Isoxazolo[3,4,5-de]isoquinoline CAS 885676-07-3

Description

The occurrence of 2H-Isoxazolo[3,4,5-de]isoquinoline is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2H-Isoxazolo[3,4,5-de]isoquinoline (CAS 885676-07-3), molecular formula C9H6N2O and molecular weight 158.16 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2H-Isoxazolo[3,4,5-de]isoquinoline (C9H6N2O) is characterized by a nitrogen-containing heterocyclic scaffold, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), 2H-Isoxazolo[3,4,5-de]isoquinoline 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.
