Chemical Structure

Cis-3,4-dichlorocyclobutene CAS 2957-95-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Cis-3,4-dichlorocyclobutene.

CATO supplies Cis-3,4-dichlorocyclobutene (CAS 2957-95-1), a certified reference material (molecular formula C4H4Cl2, MW 122.98 g/mol) for analytical method development and quality control.

Cis-3,4-dichlorocyclobutene (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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures Cis-3,4-dichlorocyclobutene 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.
