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

FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

(S)-Hexahydropyrrolo[1,2-a]pyrazin-4(1H)-one hydrochloride is a stereochemically defined heterocyclic scaffold featuring a saturated pyrazine ring fused to a pyrrolidine moiety. This bench-stable, moisture-tolerant compound serves as a key building block in medicinal chemistry, where its rigid, electron-rich core facilitates precise target engagement in bioactive molecule design.

Application

(S)-Hexahydropyrrolo[1,2-a]pyrazin-4(1H)-one hydrochloride serves as a versatile chiral building block in medicinal chemistry, enabling the construction of nitrogen-rich heterocyclic scaffolds. Its stable pyrrolidine-piperazinone core exhibits favorable functional group tolerance and facilitates downstream derivatization via amine alkylation or acylation. The hydrochloride salt enhances solubility and handling for synthetic workflows, making it well-suited for parallel synthesis and process development.
