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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+
Inaccessible (Haz class 6.1 or 9), International	$108.00+

Description

4-Bromo-1-trimethylsilyl-1-butyne features a terminal alkyne anchored by a trimethylsilyl group, enabling stable storage and selective activation. The bromine substituent provides a reactive handle for cross-coupling transformations. This molecule integrates seamlessly into Sonogashira and other palladium-catalyzed reactions, delivering efficient access to functionalized alkynes under mild conditions.

Application

4-Bromo-1-trimethylsilyl-1-butyne serves as a versatile building block in palladium-catalyzed cross-coupling reactions, enabling efficient synthesis of conjugated enynes and functionalized alkynes. The trimethylsilyl group provides enhanced stability and facilitates mild deprotection, while the terminal alkyne and bromine handle offer orthogonal reactivity for sequential transformations. Its bench-stable nature and compatibility with standard coupling protocols make it ideal for complex molecule assembly in medicinal chemistry and materials science.
