4-Chloro-3-ethoxyisoquinoline CAS 66729-01-9

Description

Compared with other compounds in its class, the molecular weight of 207.66 g/mol gives 4-Chloro-3-ethoxyisoquinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-Chloro-3-ethoxyisoquinoline (CAS 66729-01-9) is a high-purity analytical reference standard with the molecular formula C11H10ClNO and a molecular weight of 207.66 g/mol.

The molecular framework of 4-Chloro-3-ethoxyisoquinoline (C11H10ClNO) 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. 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.

CATO manufactures 4-Chloro-3-ethoxyisoquinoline 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.
