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

5-Chloro-1-methyl-1H-pyrazole-4-carbaldehyde features a reactive aldehyde group flanked by a chlorinated pyrazole ring and a methyl substituent, enabling direct coupling in heterocyclic synthesis. This bench-stable scaffold integrates readily into pharmaceutical intermediates and functional materials, offering enhanced solubility and electronic tuning for targeted applications.

Application

5-Chloro-1-methyl-1H-pyrazole-4-carbaldehyde serves as a versatile building block in medicinal chemistry, enabling efficient access to heterocyclic scaffolds via nucleophilic addition and condensation reactions. The aldehyde functionality facilitates coupling with amines, hydrazines, and other nucleophiles under mild conditions, while the chloro and methyl substituents provide orthogonal handles for further functionalization. Bench-stable and readily purified by flash chromatography, it functions effectively in multistep synthesis workflows.
