Description
CATO manufactures 3,4,5-Trimethoxyphenol 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.
3,4,5-Trimethoxyphenol (CAS 642-71-7), molecular formula C10H15N3SH2O4S and molecular weight 307.38 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H15N3SH2O4S, 3,4,5-Trimethoxyphenol contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 307.38 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.
