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

This 5-(tert-butyl) 1-ethyl 3-amino-4,6-dihydropyrrolo[3,4-c]pyrazole-1,5-dicarboxylate features a sterically shielded tert-butyl group and a bench-stable dihydropyrrolopyrazole core, enabling efficient incorporation into complex heterocyclic scaffolds. The amino and ester functionalities provide versatile handles for downstream derivatization in medicinal chemistry and materials science applications.

Application

5-(tert-Butyl) 1-ethyl 3-amino-4,6-dihydropyrrolo[3,4-c]pyrazole-1,5-dicarboxylate serves as a versatile heterocyclic building block for medicinal chemistry and synthetic organic applications. The molecule combines a stable tert-butyl group with a reactive amino functionality and two ester handles, enabling selective derivatization. Its dihydropyrrolopyrazole core provides a rigid scaffold suitable for transition metal-catalyzed coupling reactions and functional group interconversions. Bench-stable and readily purified by standard chromatography, it facilitates efficient access to complex nitrogen-containing architectures in API development workflows.
