Chemical Structure

Potassium 4-(sulfooxy)phenolate CAS 37067-27-9 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Potassium 4-(sulfooxy)phenolate (CAS 37067-27-9) is a high-purity analytical reference standard with the molecular formula C6H5O5SK and a molecular weight of 228.26 g/mol.

The molecular framework of Potassium 4-(sulfooxy)phenolate (C6H5O5SK) is characterized by a carbohydrate-derived structure, a sulfone group. 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).

As a certified reference material (CRM), Potassium 4-(sulfooxy)phenolate 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.
