Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Pyridinium, 2-ethenyl-1-methyl-, 4-methylbenzenesulfonate , homopolymer (CAS 26045-14-7), molecular formula C7H7O3SC8H10N and molecular weight 291.37 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Pyridinium, 2-ethenyl-1-methyl-, 4-methylbenzenesulfonate , homopolymer is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 291.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
CATO manufactures Pyridinium, 2-ethenyl-1-methyl-, 4-methylbenzenesulfonate , homopolymer 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.
