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

(R)-But-3-yn-2-amine hydrochloride is a chiral alkyne-containing amine featuring a stereodefined (R) configuration at the C2 position. This bench-stable, moisture-tolerant compound integrates readily into synthetic sequences requiring both nucleophilic amine and reactive terminal alkyne functionalities. Its hydrochloride salt form enhances solubility in polar solvents, facilitating use in peptide coupling, transition-metal-catalyzed cross-couplings, and click chemistry applications.

Application

(R)-But-3-yn-2-amine hydrochloride serves as a versatile chiral building block for the synthesis of functionalized alkynes and nitrogen-containing heterocycles. Its terminal alkyne functionality enables efficient copper-catalyzed coupling reactions, while the amine group offers facile derivatization and protection. The hydrochloride salt enhances solubility and stability, facilitating handling and purification in standard organic workflows.
