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

1,4-Dimethyl-1H-pyrazole features a substituted pyrazole core with methyl groups at the 1- and 4-positions, enhancing solubility and stability. This bench-stable heterocycle integrates readily into synthetic scaffolds for medicinal chemistry and materials science. Its electron-rich nature supports diverse coupling reactions and enables efficient incorporation into functional molecular architectures.

Application

1,4-Dimethyl-1H-pyrazole serves as a versatile heterocyclic building block in medicinal chemistry and process development. Its stable pyrazole core exhibits favorable functional group tolerance and facilitates diverse transformations including electrophilic substitution and transition-metal-catalyzed coupling reactions. The methyl groups enhance solubility and metabolic stability, enabling efficient incorporation into bioactive scaffolds. This compound functions effectively as a synthetic intermediate for API candidates and is well-suited for scale-up due to its bench-stable nature and straightforward purification.
