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+

Description

3-Bromo-1-ethyl-1H-pyrazole is a halogenated pyrazole derivative featuring a bromine atom at the 3-position and an ethyl group at nitrogen-1. This configuration imparts enhanced electrophilicity and stability under standard conditions, enabling efficient coupling in transition-metal-catalyzed reactions. The molecule serves as a key intermediate in medicinal chemistry for constructing heterocyclic scaffolds with tunable electronic properties.

Application

3-Bromo-1-ethyl-1H-pyrazole serves as a versatile building block in medicinal chemistry, enabling palladium-catalyzed cross-coupling reactions due to its stable bromo functionality. The ethyl substituent at N1 enhances solubility and modulates electronic properties, while the pyrazole core provides a robust heterocyclic scaffold with demonstrated utility in drug discovery. Its bench-stable nature and compatibility with standard reaction conditions facilitate efficient synthesis of complex targets.
