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

rel-tert-Butyl (3R,4R)-3-amino-4-ethoxypyrrolidine-1-carboxylate features a stereodefined pyrrolidine core with complementary amine and ethoxy functionalities. This bench-stable building block integrates readily into peptide-like scaffolds, offering high diastereoselectivity in asymmetric synthesis workflows.

Application

rel-tert-Butyl (3R,4R)-3-amino-4-ethoxypyrrolidine-1-carboxylate serves as a stereochemically defined building block for the synthesis of pyrrolidine-based scaffolds in medicinal chemistry. The protected amine and ethoxy group enable orthogonal functionalization, while the tert-butyl carbamate offers stability and ease of removal under mild acidic conditions. Its well-defined stereochemistry facilitates reproducible access to complex heterocycles and API intermediates via standard coupling and cyclization protocols.
