Chemical Structure
Description
The occurrence of 2,3,4-Trihydroxyacetophenone is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,3,4-Trihydroxyacetophenone (CAS 528-21-2), a certified reference material (molecular formula C8H8O4, MW 168.15 g/mol) for analytical method development and quality control.
2,3,4-Trihydroxyacetophenone (C8H8O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 2,3,4-Trihydroxyacetophenone 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.
