Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 130.57 g/mol gives 3-Methylenecyclobutanecarbonyl chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 3-Methylenecyclobutanecarbonyl chloride (CAS 98198-78-8), a certified reference material (molecular formula C6H7ClO, MW 130.57 g/mol) for analytical method development and quality control.
Based on its molecular formula C6H7ClO, 3-Methylenecyclobutanecarbonyl chloride contains a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 130.57 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
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 3-Methylenecyclobutanecarbonyl chloride 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.
