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

Ethyl 2-(4-bromo-1H-pyrazol-1-yl)acetate is a bench-stable, moisture-tolerant building block featuring a brominated pyrazole moiety and an ester-functionalized side chain. This structure enables direct coupling in cross-coupling reactions and facilitates incorporation into bioactive heterocyclic scaffolds.

Application

Ethyl 2-(4-bromo-1H-pyrazol-1-yl)acetate serves as a versatile building block in heterocyclic synthesis, enabling efficient access to pyrazole-based scaffolds. The bromine substituent facilitates palladium-catalyzed cross-coupling reactions, while the ester functionality supports further derivatization via hydrolysis or reduction. This compound exhibits excellent bench stability and compatibility with standard reaction conditions, making it ideal for iterative synthetic campaigns in medicinal chemistry and process development.
