Description
CATO manufactures 2,5-Bis(methylthio)terephthalaldehyde 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.
CATO supplies 2,5-Bis(methylthio)terephthalaldehyde (CAS 1399690-77-7), a certified reference material (molecular formula C10H10O2S2, MW 226.32 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H10O2S2, 2,5-Bis(methylthio)terephthalaldehyde 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 226.32 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.
