3,4-Bis{[dimethyl(2-methyl-2-propanyl)silyl]oxy}benzaldehyde(CAS: 99815-16-4)

3,4-Bis{[dimethyl(2-methyl-2-propanyl)silyl]oxy}benzaldehyde is a crystalline solid with a molecular weight of approximately 468.62 g/mol. It is slightly soluble in water but soluble in organic solvents like ethanol and acetone. The compound has a moderate reactivity, particularly in silylation reactions and can undergo hydrolysis in basic conditions. It is stable under normal conditions but should be stored in a dry, cool place away from moisture and heat sources.

3,4-Bis{[dimethyl(2-methyl-2-propanyl)silyl]oxy}benzaldehyde is typically synthesized through a silylation reaction of benzaldehyde with dimethyl(2-methyl-2-propanyl)silanol in the presence of a catalytic amount of an acid such as hydrochloric acid. The reaction is carried out under anhydrous conditions to maximize yield and selectivity. The product is isolated by recrystallization or distillation.

3,4-Bis{[dimethyl(2-methyl-2-propanyl)silyl]oxy}benzaldehyde is used in the pharmaceutical industry for the synthesis of certain organic compounds and in the polymer industry as a precursor for functionalized polymers. It is also utilized in the development of sensors and semiconductors due to its specific chemical properties.

Proper safety precautions must be taken when handling 3,4-Bis{[dimethyl(2-methyl-2-propanyl)silyl]oxy}benzaldehyde. Always wear appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. Ensure the work is conducted in a well-ventilated area or under a fume hood. Spills should be cleaned up immediately using appropriate absorbents and disposed of according to local regulations. Refer to the Safety Data Sheet (SDS) for detailed information on handling and storage.
