Chemical Structure
Description
Potassium 3-phenylpropiolate (CAS 63704-44-9), molecular formula C9H5O2K and molecular weight 184.23 g/mol, is a CATO reference standard with documented purity and traceability.
Potassium 3-phenylpropiolate (C9H5O2K) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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 Potassium 3-phenylpropiolate 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.
