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+
Accessible (Haz class 3, 4, 5 or 8), International	$238.00+

Description

N-tert-Butoxycarbonyl-1-amidinopyrazole features a protected amidine group flanked by a pyrazole ring, enabling selective incorporation into complex scaffolds. This bench-stable derivative facilitates efficient access to functionalized heterocycles in medicinal chemistry and peptide modification workflows.

Application

N-tert-Butoxycarbonyl-1-amidinopyrazole serves as a stable, bench-ready building block for the synthesis of amidinopyrazole scaffolds prevalent in medicinal chemistry. Its tert-butoxycarbonyl (Boc) group enables straightforward protection and deprotection, while the amidine functionality participates reliably in standard coupling reactions. The molecule exhibits excellent functional group tolerance and facilitates efficient access to bioactive heterocycles through well-established transformation pathways.
