http://www.leishapharma.com/1-4-dioxane.htm http://www.leishapharma.com/1-4-dioxane.htm Thu, 08 Jun 2017 00:00:00 +0530 1,4-Dioxane is a heterocyclic organic compound, classified as an ether. It is a colorless liquid with a faint sweet odor similar to that of diethyl ether. The compound is often called simply dioxane because the other dioxane isomers (1,2- and 1,3-) are rarely encountered. Chemical Name: 1,4-DIOXANE Molecular Formula: C4H8O2 Formula Weight: 88.11 CAS No.: 123-91-1 MOL File: Mol file 1-1-Carbonyldiimidazole http://www.leishapharma.com/1-1-carbonyldiimidazole.htm http://www.leishapharma.com/1-1-carbonyldiimidazole.htm Thu, 08 Jun 2017 00:00:00 +0530 1,1'-Carbonyldiimidazole (CDI) is an organic compound with the molecular formula (C3H3N2)2CO. It is a white crystalline solid. It is often used for the coupling of amino acids for peptide synthesis and as a reagent in organic synthesis.
