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

tert-Butyl pyrrolidine-3-carboxylate serves as a robust, bench-stable building block in synthetic organic chemistry. The tert-butyl ester group enables facile deprotection under mild acidic conditions, while the pyrrolidine-3-carboxylate scaffold provides a rigid, nitrogen-rich core ideal for peptide mimetics and bioactive molecule synthesis.

Application

tert-Butyl pyrrolidine-3-carboxylate serves as a versatile building block in medicinal chemistry, enabling efficient access to pyrrolidine-containing scaffolds via standard deprotection protocols. The tert-butyl ester group provides excellent bench stability and facilitates straightforward purification, while the pyrrolidine ring offers favorable conformational properties for target engagement. It participates reliably in amide coupling, reductive amination, and metal-catalyzed cross-coupling reactions, making it a practical choice for fragment-based drug discovery and macrocycle synthesis.
