Product Functions
- Radical Reducing Agent: Efficiently reduces halides (Cl, Br, I), selenides, and other radical precursors to the corresponding hydrocarbons.
- Radical Mediator: Initiates and propagates radical chain reactions in polymerization and functionalization.
- Hydrosilylation Agent: Adds Si-H group across unsaturated bonds (C=C, C=O) under radical conditions.
- Dehalogenation Agent: Cleanly removes halogen atoms from organic molecules without strong bases or metals.
- Hydrogen Source: Provides a mild and selective source of hydrogen for radical reactions.
Application Areas
- Organic Synthesis: Key intermediate in the synthesis of complex molecules, and natural products. Used for dehalogenation in multi-step sequences.
- Polymer Science & Radical Polymerization: As a radical initiator/chain transfer agent for controlled polymerization (e.g., RAFT) and synthesis of functional polymers.
- Materials Chemistry: Surface modification, preparation of silicon-based materials and nanocomposites.
- Radical Chemistry Research: Fundamental tool in mechanistic studies and development of new radical methodologies.
- Lab Automation & Flow Chemistry: Suitable for continuous processes due to its liquid form and predictable reactivity.
Manufacturing Process
TTMSS is manufactured through a high-purity, multi-step synthesis under stringent controlled conditions:

FAQ
Q1: Is TTMSS safer than tributyltin hydride?
A: Yes. TTMSS is non-toxic, avoids toxic tin residues, and is easier to handle, making it a safer and environmentally friendlier alternative.
Q2: What reactions can TTMSS replace tin hydride in?
A: It effectively replaces tin hydride in almost all radical reductions, including dehalogenations, reductive cyclizations, and desulfurizations.
Q3: How should TTMSS be stored and handled?
A: Store under dry nitrogen or argon at 2-8°C. Always handle with standard anhydrous techniques using syringes or cannula to prevent moisture exposure.
Q4: Can TTMSS be used in aqueous or protic media?
A: No. TTMSS is moisture-sensitive and reacts violently with water or alcohols. It must be used in anhydrous organic solvents.
Q5: What is the typical reaction temperature for TTMSS?
A: Reactions are often conducted at room temperature or mild heating (50-80°C), frequently using UV light or a radical initiator like AIBN.
Q6: Do you offer technical support for using TTMSS?
A: Absolutely. We provide detailed application notes, reaction protocols, and direct access to our technical team for consultation.
Q7: Is bulk/industrial quantity available?
A: Yes. We supply from gram-scale laboratory quantities to multi-kilogram industrial batches. Contact us for a custom quote.
Q8: What documentation is provided?
A: Each shipment includes Certificate of Analysis (CoA), Material Safety Data Sheet (MSDS/SDS), and full chemical documentation.
