Basic Information and Parameters<\/h2>\n<p>Dimethyl Acetylenedicarboxylate, with the CAS number 762 - 42 - 5, is a high - quality chemical compound. Its molecular formula is C\u2086H\u2086O\u2084 and its molecular weight is approximately 142.11 g\/mol. This product is presented as a clear, colorless to slightly yellow liquid under normal conditions. It has a characteristic odor. The boiling point of Dimethyl Acetylenedicarboxylate is around 170 - 172\u00b0C at 760 mmHg, and its density is about 1.15 g\/cm\u00b3. It is soluble in common organic solvents such as ethanol, acetone, and chloroform, but has limited solubility in water.<\/p>\n<h2 id=\"uses\">2. Product Uses<\/h2>\n<p>Dimethyl Acetylenedicarboxylate is widely used in the field of organic synthesis. It serves as a valuable building block for the construction of various heterocyclic compounds. For example, it can participate in Diels - Alder reactions to form complex cyclic structures, which are important intermediates in the synthesis of pharmaceuticals, agrochemicals, and fine chemicals. In the pharmaceutical industry, the derivatives obtained from Dimethyl Acetylenedicarboxylate can be used in the development of new drugs with potential biological activities. In the production of functional materials, it can be used to modify polymers, enhancing their mechanical properties and chemical stability.<\/p>\n<h2 id=\"usage\">3. Product Usage<\/h2>\n<p>When using Dimethyl Acetylenedicarboxylate, proper protective measures should be taken. Wear appropriate personal protective equipment, including safety goggles, gloves, and a lab coat. It should be used in a well - ventilated area, preferably under a fume hood to avoid inhalation of vapors. For handling, use clean and dry glassware. When measuring the compound, use calibrated pipettes or burettes. Store the product in a cool, dry place away from heat sources, oxidizing agents, and strong bases. Before use, it is recommended to check the purity of the product through appropriate analytical methods such as NMR or HPLC to ensure the accuracy of the reaction.<\/p>\n<h2 id=\"use_cases\">4. Detailed Use Cases<\/h2>\n<p>\n    <strong>Case 1: Synthesis of a Pharmaceutical Intermediate<\/strong><br \/>\n    In a research project aiming to develop a new anti - inflammatory drug, Dimethyl Acetylenedicarboxylate was used as a key starting material. A chemist mixed Dimethyl Acetylenedicarboxylate with a specific diene compound in anhydrous toluene under reflux conditions. The Diels - Alder reaction occurred, forming a cyclic intermediate. After purification by column chromatography, the yield of the desired intermediate was 70%. This intermediate was further modified through a series of chemical reactions to obtain the final drug candidate. The use of Dimethyl Acetylenedicarboxylate provided a reliable and efficient way to construct the core structure of the drug.<br \/>\n    <strong>Case 2: Polymer Modification<\/strong><br \/>\n    A materials scientist was working on improving the performance of a polyester polymer. Dimethyl Acetylenedicarboxylate was added to the polymerization reaction system in a certain proportion. The acetylenic groups in Dimethyl Acetylenedicarboxylate reacted with the functional groups of the polyester chain, resulting in cross - linking. After the reaction, the modified polymer had significantly improved mechanical strength and solvent resistance. Tensile tests showed that the tensile strength of the modified polymer increased by 30% compared to the original polymer.<\/p>\n<h2 id=\"contact\">5.
