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 N-[(2R)-but-3-yn-2-yl]carbamate features a chiral propargylic alcohol moiety flanked by a sterically hindered tert-butyl carbamate group, enabling selective protection in asymmetric synthesis. The alkyne handle facilitates efficient coupling reactions under mild conditions, while the bench-stable carbamate remains intact through standard organic transformations.

Application

tert-Butyl N-[(2R)-but-3-yn-2-yl]carbamate serves as a versatile chiral building block for the synthesis of functionalized amino alcohols and nitrogen-containing heterocycles. Its propargylic carbamate functionality enables reliable copper-catalyzed azide-alkyne cycloaddition (CuAAC), while the tert-butyl carbamate group offers excellent stability and ease of removal under mild acidic conditions. The (2R)-stereochemistry provides defined stereocontrol in downstream transformations, making it valuable for medicinal chemistry and process-oriented synthesis.
