Chemical Structure

7-amino-1,2-dihydroisoquinolin-1-one hydrochloride CAS 1909309-90-5 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-amino-1,2-dihydroisoquinolin-1-one hydrochloride.

7-amino-1,2-dihydroisoquinolin-1-one hydrochloride (CAS 1909309-90-5), molecular formula C9H8N2OHCl and molecular weight 196.63 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 7-amino-1,2-dihydroisoquinolin-1-one hydrochloride (C9H8N2OHCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 196.63 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 7-amino-1,2-dihydroisoquinolin-1-one hydrochloride 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.
