Chemical Structure
Description
4-(1-Pyrenyl)butyramide (CAS 71942-36-4), molecular formula C20H17NO and molecular weight 287.36 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 4-(1-Pyrenyl)butyramide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 287.36 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 4-(1-Pyrenyl)butyramide 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.
