Description
CATO supplies (E)-benzo[d][1,3]dioxole-5-carbaldehyde O-thiophene-2-carbonyl oxime (CAS 111172-14-6), a certified reference material (molecular formula C13H9NO4S, MW 275.28 g/mol) for analytical method development and quality control.
(E)-benzo[d][1,3]dioxole-5-carbaldehyde O-thiophene-2-carbonyl oxime (C13H9NO4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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).
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 (E)-benzo[d][1,3]dioxole-5-carbaldehyde O-thiophene-2-carbonyl oxime 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.
