Description
CATO manufactures Sodium 5-formylfuran-2-sulfonate 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 5-formylfuran-2-sulfonate (CAS 31795-44-5) is a high-purity analytical reference standard with the molecular formula C5H4O5SNa and a molecular weight of 199.13 g/mol.
Structurally, Sodium 5-formylfuran-2-sulfonate (C5H4O5SNa) contains a carbohydrate-derived structure, a sulfone group. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 199.13 g/mol, it falls into the medium-molecular-weight range. 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.
