(E)-3-Chloroacrylonitrile CAS 3721-38-8 chemical structure

Description

(E)-3-Chloroacrylonitrile (CAS 3721-38-8), molecular formula C3H2ClN and molecular weight 87.51 g/mol, is a CATO reference standard with documented purity and traceability.

(E)-3-Chloroacrylonitrile (C3H2ClN) contains a nitrile group, 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.

CATO manufactures (E)-3-Chloroacrylonitrile 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.
