Chemical Structure

1,2-Dichloro-4-(3-chlorobut-3-en-1-yl)benzene CAS 951893-00-8 chemical structure

Description

1,2-Dichloro-4-(3-chlorobut-3-en-1-yl)benzene (CAS 951893-00-8) is a high-purity analytical reference standard with the molecular formula C10H9Cl3 and a molecular weight of 235.54 g/mol.

1,2-Dichloro-4-(3-chlorobut-3-en-1-yl)benzene (C10H9Cl3) contains chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
