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

tert-Butyl (R)-4-amino-3,3-difluoropyrrolidine-1-carboxylate delivers a chiral, electron-deficient pyrrolidine scaffold with enhanced metabolic stability. The tert-butyl ester facilitates handling and purification, while the 3,3-difluoro substitution imparts conformational rigidity and improved membrane permeability. This building block integrates efficiently into peptidomimetics and bioactive small molecules.

Application

tert-Butyl (R)-4-amino-3,3-difluoropyrrolidine-1-carboxylate serves as a stereochemically defined building block for the synthesis of fluorinated pyrrolidine scaffolds. The tert-butyl carbamate group provides stability and facilitates straightforward deprotection under mild acidic conditions. The 3,3-difluoro substitution enhances metabolic stability and modulates basicity, while the primary amine enables diverse functionalization, including acylation, alkylation, and incorporation into peptide-like motifs via standard coupling protocols.
