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

2-Butyn-1-amine, hydrochloride delivers a reactive alkyne handle and primary amine functionality in a single, bench-stable salt form. This bifunctional scaffold enables efficient conjugation workflows in click chemistry, bioconjugation, and polymer synthesis under standard conditions. The protonated amine enhances solubility in aqueous media while preserving alkyne integrity for downstream transformations.

Application

2-Butyn-1-amine, hydrochloride serves as a versatile building block in synthetic organic chemistry, enabling efficient access to conjugated enamine and amide derivatives via nucleophilic addition or coupling reactions. Its terminal alkyne functionality supports reliable copper-catalyzed azide-alkyne cycloaddition (CuAAC) for triazole formation, while the primary amine group facilitates straightforward derivatization. The hydrochloride salt enhances bench stability and simplifies handling, making it well-suited for multistep synthesis and high-throughput screening workflows.
