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

Ethyl 3-ethyl-1H-pyrazole-4-carboxylate features a pyrazole core with strategically positioned ethyl and ester groups, enabling direct incorporation into heterocyclic scaffolds. This bench-stable reagent facilitates efficient access to biologically relevant pyrazole derivatives through coupling and cyclization reactions under standard conditions.

Application

Ethyl 3-ethyl-1H-pyrazole-4-carboxylate serves as a versatile building block in heterocyclic synthesis, enabling efficient access to substituted pyrazole scaffolds via standard functional group manipulations. The ethyl ester facilitates straightforward hydrolysis and coupling reactions, while the 3-ethyl substituent provides steric and electronic modulation for downstream derivatization. Its bench-stable nature and compatibility with common reaction conditions make it well-suited for medicinal chemistry campaigns and process development workflows.
