3-Chloropropyltrichlorosilane CAS 2550-06-3

1. 3-Chloropropyltrichlorosilane CAS 2550-06-3 is primarily used as a key intermediate in the production of various silane coupling agents, which are crucial for enhancing adhesion between organic and inorganic materials in coatings, adhesives, and sealants .
2. 3-Chloropropyltrichlorosilane is employed in surface modification and materials science, such as covalently bonding polymers like polyethyleneimine (PEI) to fused silica capillaries to create stable anodic electroosmotic flow for capillary electrophoresis applications .
3. 3-Chloropropyltrichlorosilane is utilized in chromatography for synthesizing silica-based anion exchangers by copolymerizing it with other silanes, enabling the effective separation of common inorganic anions like nitrite and nitrate .
4. Researchers also use this compound as a reagent to anchor functional groups onto surfaces for developing drug delivery systems, biosensors, and other advanced biomedical materials .

1. 3-Chloropropyltrichlorosilane CAS 2550-06-3 must be stored in a tightly sealed container under inert gas (e.g., nitrogen or argon) in a cool, dry, and well-ventilated environment, protected from moisture, as it reacts violently with water .
2. 3-Chloropropyltrichlorosilane is classified with GHS hazard statements H314 (Causes severe skin burns and eye damage) and H302 (Harmful if swallowed), with signal word "Danger" . It is also highly flammable, with flash points ranging from 69-84°C .
3. Personnel must wear chemical-resistant gloves, tightly fitting safety goggles with side-shields, face protection, and impervious protective clothing when handling this substance. Use only in a chemical fume hood and avoid breathing vapors, mists, or dust .
4. Keep away from heat, sparks, open flames, and incompatible materials such as strong oxidizing agents, strong bases, and water. Store locked up, and follow precautionary statements.

1. Isolate the spill area immediately, ensure adequate ventilation, and remove all sources of ignition. Evacuate non-essential personnel and wear full personal protective equipment including self-contained breathing apparatus (SCBA) .
2. DO NOT GET WATER on spilled substance or inside containers. Cover spills with DRY earth, DRY sand, or other non-combustible materials. A vapor-suppressing alcohol-resistant foam may be used to reduce vapors .
3. Collect 3-Chloropropyltrichlorosilane using clean, non-sparking tools and place into loosely covered plastic containers for later disposal. Avoid creating vapors or mists during cleanup .
4. Prevent the product from entering drains or water courses, as discharge into the environment must be avoided. Dispose of collected material as hazardous waste according to local, state, and federal environmental regulations .

1. 3-Chloropropyltrichlorosilane CAS 2550-06-3 is a highly flammable liquid (flash point 69-84°C) that forms explosive mixtures with air. Vapors are heavier than air and may travel to distant ignition sources .
2. Use dry chemical powder, carbon dioxide, or alcohol-resistant foam to extinguish fires. Note that most foams may react with the material, releasing corrosive/toxic gases. For large fires, use water spray, fog, or alcohol-resistant foam, but do NOT use water jet directly .
3. Firefighters 3-Chloropropyltrichlorosilane must wear self-contained breathing apparatus in pressure-demand mode and full protective gear when handling burning 3-chloropropyltrichlorosilane due to hazardous decomposition gases generated by thermal decomposition .
4. Under fire conditions, hazardous decomposition products include toxic fumes of carbon monoxide, carbon dioxide, and hydrogen chloride. Move containers from the fire area if safe to do so, cool exposed containers with water spray from a protected location, and contain fire runoff to prevent environmental contamination .
