Chemical Structure
Description
1-(6,7-Dichloroisoquinolin-2(1H)-yl)ethan-1-one (CAS 73261-86-6), molecular formula C11H9Cl2NO and molecular weight 242.10 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(6,7-Dichloroisoquinolin-2(1H)-yl)ethan-1-one (C11H9Cl2NO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
CATO manufactures 1-(6,7-Dichloroisoquinolin-2(1H)-yl)ethan-1-one 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.
