Cas no 99815-16-4 (3,4-Bis(tert-butyldimethylsilyloxy)benzaldehyde)

3,4-Bis(tert-butyldimethylsilyloxy)benzaldehyde is a protected benzaldehyde derivative featuring tert-butyldimethylsilyl (TBS) groups on the phenolic hydroxyl positions. This compound is particularly valuable in synthetic organic chemistry, where selective deprotection strategies are required. The TBS groups enhance stability, preventing unwanted side reactions during multi-step syntheses while allowing controlled removal under mild conditions. Its aldehyde functionality remains reactive, making it a versatile intermediate for constructing complex molecules, such as pharmaceuticals and natural products. The steric bulk of the TBS groups also improves solubility in organic solvents, facilitating handling in various reaction conditions. This compound is especially useful in protecting-group strategies for sensitive or polyfunctional substrates.
