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

tert-Butyl (1-ethynylcyclopropyl)carbamate features a strained cyclopropyl ring tethered to an ethynyl group, enabling efficient copper-catalyzed azide-alkyne cycloaddition. This stable, bench-ready building block integrates seamlessly into click chemistry workflows, delivering high-yielding triazole formation under mild conditions.

Application

tert-Butyl (1-ethynylcyclopropyl)carbamate serves as a stable, bench-ready building block for the synthesis of cyclopropyl-substituted heterocycles and bioactive molecules. Its terminal alkyne functionality enables efficient copper-catalyzed azide-alkyne cycloaddition (CuAAC), facilitating rapid access to triazole-linked scaffolds. The carbamate group provides orthogonal protection for amines, allowing selective deprotection under mild conditions. This reagent exhibits excellent functional group tolerance and is compatible with diverse reaction environments, making it ideal for modular synthetic strategies in medicinal chemistry and process development.
