Dicyclopentyl(dimethoxy)silane

Dicyclopentyl(dimethoxy)silane is an organosilicon compound with the molecular formula C12H24O2Si and CAS number 126990-35-0. This chemical features two cyclopentyl groups and two methoxy groups attached to a central silicon atom, giving it a molecular weight of 228.4 g/mol. It belongs to the family of alkoxysilanes, which are widely used as coupling agents and surface modifiers in various industrial applications requiring silicon-based chemistry.

Dicyclopentyl(dimethoxy)silane is a silicon-containing organic compound that typically appears as a liquid at room temperature. Like most alkoxysilanes, it is sensitive to moisture and can hydrolyze in the presence of water, forming silanols and releasing methanol. The compound contains hydrolyzable methoxy groups that make it reactive toward surfaces containing hydroxyl groups, enabling its function as a coupling agent in various chemical processes.

Dicyclopentyl(dimethoxy)silane is primarily used as a coupling agent and surface modifier in industrial applications. Its dual functionality allows it to bond organic materials to inorganic surfaces, making it valuable in adhesive formulations, composite materials, and surface treatments. The cyclopentyl groups provide organic compatibility while the methoxy groups enable bonding to glass, metals, and other inorganic substrates through hydrolysis and condensation reactions.

Dicyclopentyl(dimethoxy)silane must be handled with appropriate personal protective equipment due to its Skin Irrit. 2 and Eye Dam. 1 classifications. Always wear chemical-resistant gloves, safety goggles or face shield, and protective clothing. Ensure adequate ventilation to prevent vapor accumulation. Avoid skin and eye contact completely, as the substance can cause serious eye damage and skin irritation. Work in a well-ventilated area or under a fume hood when possible.

Dicyclopentyl(dimethoxy)silane should be stored in tightly sealed containers in a cool, dry place away from moisture and heat sources. Keep containers sealed when not in use to prevent hydrolysis of the methoxy groups. Store away from incompatible materials and ensure good ventilation in storage areas. The storage area should be equipped with appropriate spill containment measures and emergency washing facilities due to the substance's irritant properties.

In case of skin contact with dicyclopentyl(dimethoxy)silane, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, rinse immediately with clean water for at least 15 minutes and seek immediate medical attention due to the Eye Dam. 1 classification. If inhaled, move the person to fresh air. Seek medical attention if symptoms persist or if significant exposure has occurred.

Dicyclopentyl(dimethoxy)silane must be disposed of according to local and national hazardous waste regulations due to its aquatic toxicity classification (Aquatic Acute 1, Aquatic Chronic 1). Never discharge into drains, soil, or water bodies. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Small quantities may be neutralized through controlled hydrolysis under professional supervision, but this should only be done by qualified personnel following appropriate safety protocols.

Dicyclopentyl(dimethoxy)silane is classified as ADR Class 9 (Miscellaneous dangerous goods), Packing Group III for transport purposes. This requires appropriate dangerous goods packaging, labeling with GHS05 and GHS09 pictograms, and proper shipping documentation. Transport should comply with ADR regulations for Class 9 substances, including vehicle requirements and driver training. Ensure packages are properly secured and protected from damage during transit to prevent leakage.

Dicyclopentyl(dimethoxy)silane is subject to European REACH and CLP regulations due to its chemical classification. It must be properly classified, labeled, and supplied with safety data sheets according to CLP requirements, displaying GHS05 and GHS09 pictograms with the signal word 'Danger'. The substance is not currently listed as SVHC under REACH. Users must comply with occupational safety regulations and environmental protection requirements due to its skin, eye, and aquatic hazard classifications.
