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

Ethyl L-prolinate hydrochloride is a bench-stable, moisture-tolerant ester derivative of L-proline, featuring a polar ethyl ester group and a protonated amine. This zwitterionic form enhances solubility in aqueous and polar organic media, enabling seamless integration into peptide coupling sequences and chiral synthesis workflows.

Application

Ethyl L-prolinate hydrochloride serves as a stable, bench-ready chiral building block for peptide and heterocyclic synthesis. Its well-defined stereochemistry and compatibility with standard coupling conditions enable reliable incorporation into complex molecular architectures. The hydrochloride salt enhances solubility and simplifies purification, while the ester functionality supports selective transformations in multistep sequences.
