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

3-(4-Bromo-1H-pyrazol-1-yl)pyridine features a brominated pyrazole moiety linked to a pyridine ring, enabling efficient coupling in cross-coupling reactions. The electron-deficient pyridine and halogenated pyrazole provide complementary reactivity for transition metal-catalyzed transformations. This scaffold serves as a key building block in medicinal chemistry and materials science.

Application

3-(4-Bromo-1H-pyrazol-1-yl)pyridine serves as a versatile building block for constructing bioactive heterocyclic scaffolds. The bromopyrazole moiety enables palladium-catalyzed cross-coupling reactions, while the pyridine ring offers orthogonal reactivity for further functionalization. Bench-stable and readily purified by column chromatography, it facilitates efficient synthesis of pharmaceutical intermediates and agrochemical candidates through established coupling protocols.
