Chemical Structure
Description
1,3-Butadiene, 2,3-dichloro-, polymer with 2-chloro-1,3-butadiene (CAS 25067-95-2) is a high-purity analytical reference standard with the molecular formula C4H4Cl2C4H5Cl and a molecular weight of 211.51 g/mol.
Structurally, 1,3-Butadiene, 2,3-dichloro-, polymer with 2-chloro-1,3-butadiene (C4H4Cl2C4H5Cl) contains chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 211.51 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
