    HazMat Fee

    An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

    The shipment is processed through FedEx Ground under the Limited Quantity option.

    Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

    If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Description

4-Bromobutoxy-tert-butyl-dimethylsilane delivers a robust silyl-protected ether functionality with a reactive bromide handle. This bifunctional molecule enables site-specific conjugation in synthetic workflows, combining stable storage with efficient downstream transformation under standard conditions.

Application

4-Bromobutoxy-tert-butyl-dimethylsilane serves as a versatile protected alkoxide synthon, enabling efficient etherification and nucleophilic substitution reactions. The tert-butyldimethylsilyl (TBS) group provides excellent stability under basic conditions and mild acidic deprotection, while the 4-bromobutoxy moiety facilitates coupling with nucleophiles via SN2 pathways. This compound functions reliably in multistep synthesis, offering orthogonal protection and clean functionalization for complex molecule assembly.
