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.

Description

4-Bromo-1-(2-methoxyethyl)-1H-pyrazole features a bromine substituent at the C4 position and a methoxyethyl side chain at nitrogen-1, imparting enhanced solubility and synthetic versatility. This bench-stable pyrazole derivative serves as a key intermediate in medicinal chemistry, enabling efficient coupling reactions and facilitating the construction of complex heterocyclic architectures under standard conditions.

Application

4-Bromo-1-(2-methoxyethyl)-1H-pyrazole serves as a versatile building block in medicinal chemistry, enabling efficient late-stage functionalization via palladium-catalyzed cross-coupling reactions. The bromo group facilitates reliable Suzuki, Stille, and Negishi coupling transformations, while the 2-methoxyethyl side chain offers moderate solubility and compatibility with common purification methods. Its bench-stable nature and predictable reactivity make it well-suited for modular synthesis of bioactive heterocycles and API intermediates.
