Description
Dimethyl acetylene dicarboxylate is an activated alkyne diester used as a versatile building block in organic synthesis, supplied at a minimum purity of 95 %. It has CAS number 762-42-5, empirical formula C₆H₆O₄, and molar mass 142,1 g/mol. Key physical properties include a density of 1,156 g/cm³, boiling point of 95 °C, and flash point of 86 °C. is practical for cycloaddition chemistry, Michael-type additions, heterocycle construction, and multi-step route development. Chemists employ this electron-deficient acetylene in Diels–Alder and related transformations where a compact, reactive dienophile or electrophile is required. Available from manufacturer Carl ROTH for research and development laboratories. Handle as a flammable, corrosive organic liquid according to standard laboratory safety practice. Well suited to synthetic organic groups needing a reliable DMAD grade in a convenient working quantity.
