Description
As a certified reference material (CRM), 4-(Acetoacetylamino)benzenesulfonic acid sodium salt meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
4-(Acetoacetylamino)benzenesulfonic acid sodium salt (CAS 63503-98-0) is a high-purity analytical reference standard with the molecular formula C10H10NO5SNa and a molecular weight of 279.24 g/mol.
4-(Acetoacetylamino)benzenesulfonic acid sodium salt (C10H10NO5SNa) 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.
