Chemical Structure
Description
The occurrence of Benzene, 1-(chloromethyl)-4-ethenyl-, polymer with 1,4-diethenylbenzene is closely related to chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Benzene, 1-(chloromethyl)-4-ethenyl-, polymer with 1,4-diethenylbenzene (CAS 64381-83-5) is a high-purity analytical reference standard with the molecular formula C9H9ClC10H10 and a molecular weight of 282.81 g/mol.
Based on its molecular formula C9H9ClC10H10, Benzene, 1-(chloromethyl)-4-ethenyl-, polymer with 1,4-diethenylbenzene contains chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 282.81 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.
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.
