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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

5-Methyl-1H-indazol-4-amine delivers a robust heteroaromatic scaffold with enhanced solubility and stability under standard conditions. The methyl group at the 5-position confers steric and electronic tuning, while the primary amine at the 4-position enables facile derivatization. This compound serves as a key building block in medicinal chemistry for kinase inhibitors and bioactive small molecules.

Application

5-Methyl-1H-indazol-4-amine serves as a versatile building block in medicinal chemistry, enabling rapid access to bioactive heterocycles through palladium-catalyzed cross-coupling and electrophilic substitution reactions. The molecule exhibits excellent bench stability and functional group tolerance, facilitating straightforward derivatization for kinase inhibitor and CNS-targeted compound development. Its well-defined reactivity profile supports efficient synthesis of diverse indazole-based scaffolds in standard laboratory workflows.
