    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-Butylphenylacetylene features a terminal alkyne group conjugated to an electron-rich aromatic ring, enabling efficient coupling reactions in cross-coupling and click chemistry. The butyl substituent enhances solubility and reduces aggregation, improving handling under standard conditions. This compound serves as a modular building block for functionalized arenes and advanced materials.

Application

4-Butylphenylacetylene serves as a versatile building block in transition-metal-catalyzed coupling reactions, enabling efficient access to conjugated arylalkynes. Its terminal alkyne functionality facilitates Sonogashira coupling with aryl halides and other cross-coupling protocols under mild conditions. The butyl-substituted phenyl group enhances solubility and provides steric modulation, improving handling and purification in synthetic workflows. This compound functions reliably in the construction of extended π-systems and functionalized aromatic scaffolds relevant to materials science and medicinal chemistry.
