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

4-Bromo-1-methyl-5-phenyl-1H-pyrazole features a brominated pyrazole core with a methyl group at N1 and a phenyl substituent at C5, delivering a robust scaffold for medicinal chemistry. The electron-deficient pyrazole ring enables efficient coupling reactions, while the sterically accessible bromine facilitates cross-coupling transformations. This compound exhibits excellent bench stability and solubility in common organic solvents, streamlining its use in synthesis workflows.

Application

4-Bromo-1-methyl-5-phenyl-1H-pyrazole serves as a versatile building block in heterocyclic synthesis, enabling palladium-catalyzed cross-coupling reactions due to its stable bromo functionality. The methyl and phenyl substituents provide orthogonal reactivity handles, while the pyrazole core offers inherent bench stability and compatibility with standard purification methods. This compound facilitates efficient access to substituted pyrazole scaffolds relevant to medicinal chemistry and materials science applications.
