Chemical Structure
Description
The occurrence of Potassium guaiacolsulfonate hemihydrate is closely related to a carbohydrate-derived structure, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Potassium guaiacolsulfonate hemihydrate (CAS 78247-49-1) is a high-purity analytical reference standard with the molecular formula C7H7O5SKH2O and a molecular weight of 260.30 g/mol.
Based on its molecular formula C7H7O5SKH2O, Potassium guaiacolsulfonate hemihydrate contains a carbohydrate-derived structure, a sulfone group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 260.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Potassium guaiacolsulfonate hemihydrate 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.
