Chemical Structure

1,3-Dichloro-2-vinylbenzene CAS 28469-92-3 chemical structure

Description

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.

CATO supplies 1,3-Dichloro-2-vinylbenzene (CAS 28469-92-3), a certified reference material (molecular formula C8H6Cl2, MW 173.04 g/mol) for analytical method development and quality control.

Structurally, 1,3-Dichloro-2-vinylbenzene (C8H6Cl2) contains chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 173.04 g/mol, it falls into the medium-molecular-weight range. 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.
