Dimethoxy-di(propan-2-yl)silane is an organosilicon compound with the molecular formula C8H20O2Si and CAS number 18230-61-0. This chemical features two isopropyl groups and two methoxy groups attached to a silicon atom, giving it a molecular weight of 176.33 g/mol. It belongs to the family of alkoxysilanes and is classified as a flammable liquid with skin irritation and sensitization properties.

Dimethoxy-di(propan-2-yl)silane is a liquid organosilicon compound at room temperature with the molecular formula C8H20O2Si. It has a molecular weight of 176.33 g/mol and contains both hydrophobic isopropyl groups and hydrolyzable methoxy groups. Like most alkoxysilanes, it is likely sensitive to moisture and may undergo hydrolysis in the presence of water, releasing methanol.

Dimethoxy-di(propan-2-yl)silane is primarily used as a coupling agent and surface modifier in various industrial applications. It serves as an intermediate in silicone synthesis, helping to improve adhesion between organic and inorganic materials. The compound is commonly employed in the production of specialized coatings, sealants, and adhesives where its dual organic-inorganic nature provides enhanced bonding properties.

Dimethoxy-di(propan-2-yl)silane requires careful handling due to its flammable and skin-sensitizing properties. Wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing to prevent skin contact. Ensure adequate ventilation and keep away from ignition sources. Use in well-ventilated areas to avoid inhalation of vapors, as the compound can cause skin irritation and sensitization.

Dimethoxy-di(propan-2-yl)silane should be stored in a cool, dry, well-ventilated area away from heat sources and ignition points due to its flammable nature. Keep containers tightly sealed to prevent moisture contamination, as the compound is sensitive to humidity. Store separately from strong oxidizers and incompatible materials. Maintain temperatures below recommended limits and ensure proper labeling with GHS02 and GHS07 pictograms.

In case of skin contact with dimethoxy-di(propan-2-yl)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 plenty of clean water and seek medical attention. If inhaled, move to fresh air immediately. Due to its skin sensitization properties, monitor for allergic reactions and seek medical advice if irritation persists.

Dimethoxy-di(propan-2-yl)silane must be disposed of according to local and national hazardous waste regulations due to its flammable and potentially harmful properties. Contact licensed waste disposal companies for proper treatment and disposal. Do not pour down drains or release into the environment, as it is classified as Aquatic Chronic 3. Empty containers should also be handled as hazardous waste and disposed of through appropriate channels.

Dimethoxy-di(propan-2-yl)silane is classified under ADR Class 3 (flammable liquids), Packing Group III for transportation purposes. It must be transported in appropriate UN-approved packaging with proper labeling and documentation. Vehicles must comply with ADR regulations for Class 3 substances, including appropriate safety equipment and driver training. Ensure packages are properly sealed and marked with the correct shipping name and identification numbers.

Dimethoxy-di(propan-2-yl)silane is subject to standard European chemical regulations including REACH and CLP classification requirements. It is classified with hazard classes Flam.
