Chemical Structure
Description
5-Hydroxyisoindolin-1-one (CAS 252061-66-8), molecular formula C8H7NO2 and molecular weight 149.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 5-Hydroxyisoindolin-1-one is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 149.15 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5-Hydroxyisoindolin-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.
