Description
CATO manufactures 2,5-dichloro-3-(chloromethyl)thiophene 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-dichloro-3-(chloromethyl)thiophene (CAS 10095-91-7), a certified reference material (molecular formula C5H3Cl3S, MW 201.50 g/mol) for analytical method development and quality control.
2,5-dichloro-3-(chloromethyl)thiophene (C5H3Cl3S) contains sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
