Chemical Structure

1,3-Dichloro-5-vinylbenzene CAS 2155-42-2 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-5-vinylbenzene (CAS 2155-42-2), a certified reference material (molecular formula C8H6Cl2, MW 173.04 g/mol) for analytical method development and quality control.

Based on its molecular formula C8H6Cl2, 1,3-Dichloro-5-vinylbenzene contains chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 173.04 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
