Description
CATO manufactures (4-Chlorobut-2-yn-1-yl)benzene 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.
(4-Chlorobut-2-yn-1-yl)benzene (CAS 33598-24-2) is a high-purity analytical reference standard with the molecular formula C10H9Cl and a molecular weight of 164.63 g/mol.
Owing to chlorine substitution, an aromatic ring system, (4-Chlorobut-2-yn-1-yl)benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 164.63 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.
