Chemical Structure

6-Methoxy-5-nitro-isoquinoline 6-Methoxy-5-nitroisoquinoline 72677-92-0 CAS 72677-92-0 chemical structure

Description

The occurrence of 6-Methoxy-5-nitro-isoquinoline 6-Methoxy-5-nitroisoquinoline 72677-92-0 is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6-Methoxy-5-nitro-isoquinoline 6-Methoxy-5-nitroisoquinoline 72677-92-0 (CAS 72677-92-0) is a high-purity analytical reference standard with the molecular formula C10H8N2O3 and a molecular weight of 204.18 g/mol.

The molecular framework of 6-Methoxy-5-nitro-isoquinoline 6-Methoxy-5-nitroisoquinoline 72677-92-0 (C10H8N2O3) is characterized by an amino-acid-derived structure, 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), 6-Methoxy-5-nitro-isoquinoline 6-Methoxy-5-nitroisoquinoline 72677-92-0 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.
