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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+
Inaccessible (Haz class 6.1 or 9), International	$108.00+

Description

(R)-2-Aminopent-4-ynoic acid hydrochloride features a chiral α-amino acid scaffold with a terminal alkyne handle, enabling bioorthogonal conjugation in peptide and probe synthesis. The hydrochloride salt enhances solubility and stability under standard bench conditions, facilitating straightforward handling in aqueous and organic media. This derivative integrates efficiently into diverse molecular architectures through click chemistry or amide coupling protocols.

Application

(R)-2-Aminopent-4-ynoic acid hydrochloride serves as a versatile building block for the synthesis of bioactive heterocycles and peptidomimetics. Its terminal alkyne and α-amino carboxylic acid functionalities enable efficient copper-catalyzed azide-alkyne cycloaddition (CuAAC) and direct incorporation into peptide chains. The hydrochloride salt enhances bench stability and simplifies handling, while the stereochemically defined (R)-configuration ensures predictable reactivity in asymmetric synthesis.
