{"product_id":"cis-1-2-dichloroethene-2k4y-2k4y","title":"cis-1,2-Dichloroethene, min. 95 %, 2 g","description":"\u003cp\u003ecis-1,2-Dichloroethene is a chlorinated alkene reagent offered at a minimum purity of 95 % for synthetic and analytical laboratory use. Identified by CAS number 156-59-2 and empirical formula C₂H₂Cl₂, it has a molar mass of 96,94 g\/mol and a density of 1,238 g\/cm³. Key physical data include a boiling point of 60 °C and a flash point of 6 °C, which are important for reaction setup, distillation planning, and safe handling of this low-boiling liquid. The cis isomer is relevant in organohalogen chemistry, solvent studies, and as a reference or intermediate where defined stereochemistry of 1,2-dichloroethene is required. This listing provides size appropriate for small-scale experiments and method development. Material from manufacturer Carl ROTH is presented with the stated identity and physicochemical parameters to support reproducible laboratory work.
