Chemical Structure

3,4-Dichlorocyclobut-1-ene CAS 41326-64-1 chemical structure

Description

3,4-Dichlorocyclobut-1-ene (C4H4Cl2) 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.

3,4-Dichlorocyclobut-1-ene (CAS 41326-64-1) is a high-purity analytical reference standard with the molecular formula C4H4Cl2 and a molecular weight of 122.98 g/mol.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 3,4-Dichlorocyclobut-1-ene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
