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-Methoxybenzyl)-1H-pyrazol-5-amine features a pyrazole core functionalized with a methoxy-substituted benzyl group and an amine at the C5 position, enabling integration into diverse heterocyclic scaffolds. The electron-donating methoxy group enhances solubility and stabilizes reactive intermediates. This compound serves as a key building block for medicinal chemistry campaigns targeting kinase inhibitors and bioactive nitrogen-rich frameworks.

Application

1-(4-Methoxybenzyl)-1H-pyrazol-5-amine serves as a versatile building block for medicinal chemistry and heterocyclic synthesis. Its pyrazole core provides a rigid, electron-rich scaffold with defined regiochemistry, while the 4-methoxybenzyl group offers orthogonal handle for further functionalization or deprotection under mild conditions. The molecule exhibits excellent bench stability and facilitates efficient coupling reactions, making it well-suited for the construction of diverse API-relevant architectures in drug discovery workflows.
