Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-Ethynylazetidine (CAS 1207840-08-1), molecular formula C5H7N and molecular weight 81.12 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, 3-Ethynylazetidine is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 81.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 3-Ethynylazetidine 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.
