DMSO as a C1 Source
Request A Sample Activated dimethyl sulfoxide can donate a methylene, methyl, carbonyl, or methylthio unit into a new bond, replacing formaldehyde, carbon monoxide, or toxic methylating agents in modern synthesis. It is now a practical C1 building block for heterocycle and specialty chemical manufacture. Because DMSO is inexpensive, abundant, and of relatively low toxicity, this…

DMSO as a Sulfur Source for Thiophene Synthesis
Request A Sample Activated dimethyl sulfoxide can donate the sulfur atom in thiophene ring formation, replacing malodorous P₂S₅, Lawesson’s reagent, or elemental sulfur. It now serves as both solvent and sulfur donor for the heterocycle classes found in drugs and organic electronics. Classical thiophene syntheses carry a sulfur-related environmental cost, and DMSO offers a lower-odor,…

DMSO Grades Explained
Request A Sample DMSO is sold in industrial, pharmaceutical, and electronic grades defined by assay, water, trace metals, and dimethyl sulfide. The grade purchased decides whether a precious-metal catalyst survives, an API passes release, or a wafer stays defect-free. Buying above need raises cost; buying below it fails the process. Grade Specifications Parameter Industrial Pharmaceutical…

Cyanation Reaction in DMSO
Request A Sample Converting alkyl and aryl halides to nitriles uses cheap inorganic cyanides — NaCN and KCN — that dissolve poorly in most organic solvents. DMSO dissolves these salts and presents the cyanide as a bare, highly nucleophilic anion, which makes it the standard medium for aliphatic and activated aromatic cyanation. R–X + NaCNDMSO,…

Corey–Chaykovsky Epoxidation
Request A Sample The Corey–Chaykovsky reaction transfers a one-carbon methylene unit from a DMSO-derived sulfoxonium salt to aldehydes, ketones, and enones, producing epoxides and cyclopropanes. DMSO is both the reaction medium and the structural parent of the ylide reagent, which makes it the standard solvent for this transformation in pharmaceutical manufacturing. R2C=O + (CH3)2S(O)=CH2NaH, DMSO/THF,…

DMSO in Anti-Tumor Drug Manufacturing
Request A Sample Dimethyl sulfoxide (DMSO) serves three distinct roles in oncology API production: a reaction solvent for reductions and heterocycle assembly, a recrystallization medium for purification, and — in one marketed drug — a structural component of the active substance itself. Where DMSO Is Used in Oncology APIs Capecitabine uses DMSO in a sodium…

DMSO in Diphenyl Ether Herbicide Manufacturing
Request A Sample Diphenyl ether herbicides — fomesafen, acifluorfen, lactofen, and oxyfluorfen — build their central diaryl ether bond (Ar–O–Ar′) by phenoxide nucleophilic aromatic substitution on an activated nitro aryl halide. This condensation is the cost- and quality-determining step of the whole route. Dimethyl sulfoxide (DMSO) is the standard industrial solvent for it, releasing reactive,…

DMSO in Azole Antifungal Manufacturing
Request A Sample Azole antifungals — imidazoles such as ketoconazole and triazoles such as voriconazole and posaconazole — attach an imidazole or 1,2,4-triazole ring to a hydrophobic side chain through an N–C bond. That coupling is an SN2 alkylation of an azolide salt, a reaction class unusually sensitive to solvent. Dimethyl sulfoxide (DMSO) is the…
