Phenoxathiine 10-oxide CAS 948-44-7 chemical structure

Description

CATO manufactures Phenoxathiine 10-oxide 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.

Phenoxathiine 10-oxide (CAS 948-44-7), molecular formula C12H8O2S and molecular weight 216.26 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C12H8O2S, Phenoxathiine 10-oxide contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 216.26 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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