Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Ethyl (2E)-3-{4-[(E)-2-(3-methyl-4-nitro-1,2-oxazol-5-yl)ethenyl]phenyl}prop-2-enoate (CAS 338395-86-1) is a high-purity analytical reference standard with the molecular formula C17H16N2O5 and a molecular weight of 328.32 g/mol.

Ethyl (2E)-3-{4-[(E)-2-(3-methyl-4-nitro-1,2-oxazol-5-yl)ethenyl]phenyl}prop-2-enoate (C17H16N2O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures Ethyl (2E)-3-{4-[(E)-2-(3-methyl-4-nitro-1,2-oxazol-5-yl)ethenyl]phenyl}prop-2-enoate 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.
