Description
CATO manufactures 3-Chloro-3-methyl-1-butene 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-Chloro-3-methyl-1-butene (CAS 2190-48-9), molecular formula C5H9Cl and molecular weight 104.58 g/mol, is a CATO reference standard with documented purity and traceability.
3-Chloro-3-methyl-1-butene (C5H9Cl) contains 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.
