Description
CATO manufactures Sodium 4-(Pivaloyloxy)benzenesulfonate 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.
Sodium 4-(Pivaloyloxy)benzenesulfonate (CAS 188114-91-2) is a high-purity analytical reference standard with the molecular formula C11H13O5SNa and a molecular weight of 280.27 g/mol.
The molecular framework of Sodium 4-(Pivaloyloxy)benzenesulfonate (C11H13O5SNa) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
