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 silicon atom, giving it a molecular weight of 228.4 g/mol. It belongs to the silane family and is classified as hazardous due to its skin irritating and eye damaging properties, as well as its aquatic toxicity.

Dicyclopentyl(dimethoxy)silane is a silicon-containing organic compound with molecular formula C12H24O2Si and molecular weight 228.4 g/mol. As an organosilane, it typically exists as a liquid at room temperature with characteristic alkoxysilane properties. The presence of methoxy groups makes it reactive with moisture, while the cyclopentyl groups contribute to its organic solubility characteristics. Specific physical properties like boiling point and density require laboratory analysis for precise determination.

Dicyclopentyl(dimethoxy)silane is primarily used as a coupling agent and surface modifier in various 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 compound is also utilized in silicone polymer synthesis and as an intermediate in specialty chemical production, particularly where enhanced adhesion or surface modification properties are required.

Dicyclopentyl(dimethoxy)silane requires careful handling due to its classification as Skin Irritant Category 2 and Eye Damage Category 1. Always wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work in well-ventilated areas or under fume extraction systems. Avoid direct contact with skin and eyes, and prevent inhalation of vapors. The GHS05 and GHS09 pictograms indicate corrosive and environmental hazards requiring special precautions.

Dicyclopentyl(dimethoxy)silane should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from moisture and incompatible materials. As an alkoxysilane, it is moisture-sensitive and should be protected from humidity to prevent hydrolysis. Store away from heat sources, ignition sources, and direct sunlight. Keep containers upright and ensure proper labeling with hazard information. Storage areas should have appropriate spill containment and emergency equipment readily available.

Immediate action is required due to the Eye Damage Category 1 classification of dicyclopentyl(dimethoxy)silane. For eye contact, rinse immediately with plenty of water for at least 15 minutes and seek medical attention urgently. For skin contact, wash thoroughly with soap and water and remove contaminated clothing. If inhaled, move to fresh air immediately. In case of ingestion, do not induce vomiting and seek medical advice. Always consult the safety data sheet for complete first aid procedures.

Dicyclopentyl(dimethoxy)silane must be disposed of as hazardous waste due to its environmental classification (Aquatic Acute 1, Aquatic Chronic 1). Contact licensed hazardous waste disposal companies for proper treatment and disposal. Never discharge to sewers, waterways, or soil. Small quantities can be allowed to hydrolyze under controlled conditions before disposal, but this should only be done by trained personnel. Always follow local environmental regulations and consult the safety data sheet for specific disposal requirements.

Dicyclopentyl(dimethoxy)silane is classified as ADR Class 9 (Miscellaneous Dangerous Substances), Packing Group III for transportation purposes. This classification requires appropriate UN-specification packaging and proper shipping documentation including dangerous goods declarations. Vehicles must carry appropriate emergency equipment and drivers need ADR certification for Class 9 materials. Packages must display the correct hazard labels and orientation arrows where applicable, following international dangerous goods regulations.

Dicyclopentyl(dimethoxy)silane is subject to European REACH regulation requiring registration for manufacture or import above one tonne per year. It falls under CLP regulation for classification and labeling as indicated by its hazard classes and GHS pictograms. The substance is not currently listed as an SVHC (Substance of Very High Concern). Users must comply with occupational health and safety regulations, environmental protection laws, and transportation regulations (ADR) when handling this chemical.
