Chemical Structure
Description
(4-Bromo-2-thienyl)methanol (CAS 79757-77-0), molecular formula C5H5BrOS and molecular weight 193.06 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, (4-Bromo-2-thienyl)methanol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 193.06 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.
CATO manufactures (4-Bromo-2-thienyl)methanol 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.
