Description
CATO manufactures 2-Bromo-4-octylthiophene 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-Bromo-4-octylthiophene (CAS 189102-85-0), a certified reference material (molecular formula C12H19BrS, MW 275.25 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, bromine substitution, 2-Bromo-4-octylthiophene is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 275.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
