Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 3-Chloro-4-fluoro-5,8-dihydroisoquinolin-5-ol (CAS 1236769-91-7), a certified reference material (molecular formula C9H7ClFNO, MW 199.61 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 3-Chloro-4-fluoro-5,8-dihydroisoquinolin-5-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 199.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 3-Chloro-4-fluoro-5,8-dihydroisoquinolin-5-ol 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.
