Chemical Structure

(2-bromoethylidene)cyclobutane CAS 24927-33-1 chemical structure

Description

The occurrence of (2-bromoethylidene)cyclobutane is closely related to bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(2-bromoethylidene)cyclobutane (CAS 24927-33-1) is a high-purity analytical reference standard with the molecular formula C6H9Br and a molecular weight of 161.04 g/mol.

(2-bromoethylidene)cyclobutane (C6H9Br) contains bromine 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
