Description
CATO manufactures 2-(3-Chloropropyl)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.
2-(3-Chloropropyl)thiophene (CAS 20906-17-6) is a high-purity analytical reference standard with the molecular formula C7H9ClS and a molecular weight of 160.66 g/mol.
Owing to sulfur-containing functionality, chlorine substitution, 2-(3-Chloropropyl)thiophene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 160.66 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.
