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+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+

Description

5-Bromo-3-methyl-1-phenyl-1H-pyrazole features a brominated pyrazole core with a methyl group at the 3-position and a phenyl substituent at N1, delivering enhanced electronic modulation and steric profile. This bench-stable heterocycle integrates readily into cross-coupling workflows and serves as a key scaffold in medicinal chemistry for targeted kinase inhibition and bioactive molecule construction.

Application

5-Bromo-3-methyl-1-phenyl-1H-pyrazole serves as a versatile building block in medicinal chemistry and heterocyclic synthesis. The bromo group enables palladium-catalyzed cross-coupling reactions, while the methyl and phenyl substituents provide defined steric and electronic profiles. Its stability under standard reaction conditions facilitates purification and integration into complex molecular architectures.
