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+

Description

Methyl 3,5-dichloropyrazine-2-carboxylate features a pyrazine core substituted with chlorine atoms at the 3 and 5 positions and a methyl ester at the 2 position. This electron-deficient heterocycle serves as a robust building block in medicinal chemistry, enabling efficient coupling reactions under standard conditions. The dichloro substitution enhances reactivity in cross-coupling processes, while the ester group provides a handle for further functionalization.

Application

Methyl 3,5-dichloropyrazine-2-carboxylate serves as a versatile building block in heterocyclic synthesis, enabling efficient access to substituted pyrazine scaffolds. Its dual chloro groups at C3 and C5 positions facilitate sequential nucleophilic substitution reactions, while the ester functionality supports further derivatization. The compound exhibits excellent bench stability and simplifies purification, making it well-suited for iterative coupling strategies in medicinal chemistry and API development.
