Description

Mmts CAS NO 33577-16-1 is a specialized organosulfur compound, specifically methyl methanethiosulfonate, valued for its role as a versatile chemical intermediate and a selective thiol-modifying reagent. Its primary commercial significance lies in its ability to introduce methyl disulfide bonds or serve as a methylsulfenylating agent in synthetic organic chemistry and biochemical research. This product is essential for manufacturers and R&D laboratories in the pharmaceutical, agrochemical, and biotechnology sectors, where precise chemical modification is critical for developing active ingredients and studying protein structure-function relationships.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring disulfide bridge formation or specific thiol protection.
• Bioconjugation & Protein Engineering: A key reagent for site-specific modification of cysteine residues in proteins and peptides, enabling drug conjugation, labeling, and structural studies.
• Agrochemical Synthesis: Serves as a building block in the production of certain herbicides, fungicides, and insecticides that contain sulfur-based functional groups.
• Polymer Chemistry: Employed in the synthesis of functional polymers and materials where thiol-ene click chemistry or specific surface modifications are required.
• Research & Development: A critical tool in academic and industrial R&D for studying redox biology, enzyme mechanisms, and developing new synthetic methodologies.
• Crosslinking Agent: Used to create reversible or controlled crosslinks in biomaterials and hydrogels for biomedical applications.

Quality Control

Our Mmts is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Keep away from strong acids, bases, and oxidizing agents. Due to its reactivity with thiols, store separately from reducing agents.
