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+

Description

H-Acpc-OEt·HCl is a bench-stable, moisture-tolerant building block featuring a protected acylated proline derivative with a terminal ethyl ester. This versatile scaffold integrates readily into peptide synthesis workflows, enabling direct incorporation of constrained proline motifs under standard conditions.

Application

H-Acpc-OEt·HCl serves as a stable, bench-ready building block for the synthesis of peptidomimetics and bioactive heterocycles. Its acetyl-protected proline derivative core enables straightforward incorporation into cyclic scaffolds via standard coupling and cyclization protocols. The ethyl ester facilitates downstream functionalization, while the hydrochloride salt ensures enhanced solubility and handling. Functions reliably in solid-phase and solution-phase peptide synthesis workflows.
