Product Description
Dimethyl sulfate (Methyl sulfate), 99% Methylating Agent DMS
Dimethyl sulfate (DMS) is a high-purity, highly reactive methylating agent widely employed in the synthesis of pharmaceutical, agrochemicals, dyes, and fine chemicals. Supplied as a clear, colorless to pale yellow liquid with a minimum assay of 99%, it delivers exceptional methylation efficiency for oxygen, nitrogen, and sulfur nucleophiles. Its consistent performance, combined with rigorous quality control and specialized hazardous material handling procedures, makes it a critical reagent for research laboratories and industrial manufacturers seeking reliable, large-scale methylation capability.
Key Features
- Exceptional Methylation Reactivity: Features two activated methyl groups, enabling rapid and complete methylation of a wide range of substrates under controlled conditions
- High Purity Grade: Minimum 99% assay with low acidity and minimal water content ensures predictable stoichiometry and reduces side reactions
- Consistent Industrial Quality: Manufactured under tightly monitored conditions for batch-to-batch uniformity
- Clear Liquid Form: Allows for precise volumetric metering and controlled addition in closed reaction systems
- Professional Hazard Control: Supported by extensive safety data, engineering control recommendations, and specialized packaging
Main Functions and Applications
Pharmaceutical and Agrochemical Synthesis: Primary reagent for O-methylation of phenols, carboxylic acids, and enolates, and N-methylation of amines and heterocycles. Used in manufacturing active pharmaceutical ingredients (APIs), vitamins, alkaloids, pesticides, and herbicides.
Dyestuff and Pigment Production: Used to methylate amino and hydroxyl groups in dye intermediates for azo, anthraquinone, and cationic dyes. Also used in synthesis of cationic dyes and textile auxiliaries.
Specialty Chemical and Reagent Manufacturing: Employed in production of surfactants, phase-transfer catalysts, photographic chemicals, flavors, and as laboratory reagent for academic and industrial research.
