Description
As a certified reference material (CRM), 5-bromo-3-chloro-8-methoxyisoquinoline 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.
5-bromo-3-chloro-8-methoxyisoquinoline (CAS 1696988-00-7) is a high-purity analytical reference standard with the molecular formula C10H7BrClNO and a molecular weight of 272.53 g/mol.
The molecular framework of 5-bromo-3-chloro-8-methoxyisoquinoline (C10H7BrClNO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
