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.

Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

3-Amino-5-(4-methoxyphenyl)pyrazole is a heterocyclic scaffold featuring an electron-rich pyrazole core conjugated with a para-methoxyphenyl group. This configuration imparts enhanced solubility and stability under standard bench conditions, enabling straightforward incorporation into medicinal chemistry campaigns. The amino functionality facilitates direct derivatization for probe development or macrocycle assembly.

Application

3-Amino-5-(4-methoxyphenyl)pyrazole serves as a versatile building block for heterocyclic synthesis, enabling efficient access to pyrazole-based scaffolds through standard coupling and functionalization protocols. The amino group facilitates derivatization via acylation, alkylation, or transition-metal-catalyzed cross-coupling, while the 4-methoxyphenyl substituent enhances solubility and provides a handle for further modification. Bench-stable and readily purified by recrystallization, it functions effectively in medicinal chemistry campaigns targeting kinase inhibitors and other bioactive molecules.
