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

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+

Description

tert-Butyl N-[cis-4-fluoropyrrolidin-3-yl]carbamate is a bench-stable, moisture-tolerant building block featuring a cis-configured fluorinated pyrrolidine ring. This scaffold integrates readily into bioactive molecules, where the fluorine atom enhances metabolic stability and modulates electronic properties. The tert-butyl carbamate group enables straightforward deprotection under mild acidic conditions, facilitating late-stage functionalization in medicinal chemistry campaigns.

Application

tert-Butyl N-[cis-4-fluoropyrrolidin-3-yl]carbamate serves as a key chiral building block for medicinal chemistry, enabling efficient access to fluorinated pyrrolidine scaffolds. The cis-configuration ensures predictable stereochemical control in downstream transformations. The tert-butyl carbamate group provides excellent bench stability and facilitates straightforward deprotection under mild acidic conditions. Its functional group tolerance supports integration into diverse coupling and cyclization workflows, making it a practical choice for API precursor synthesis and fragment-based drug discovery.
