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

Description

2,4-Dichloropyrazolo[1,5-a][1,3,5]triazine features a rigid, electron-deficient heterocyclic core that enables direct functionalization at the pyrazole and triazine positions. This scaffold integrates readily into synthetic routes requiring high thermal stability and predictable reactivity, particularly in medicinal chemistry and agrochemical development.

Application

2,4-Dichloropyrazolo[1,5-a][1,3,5]triazine serves as a versatile building block in medicinal chemistry, enabling efficient construction of heterocyclic scaffolds through palladium-catalyzed cross-coupling reactions. Its dichloro substitution pattern facilitates selective functionalization at C2 and C4 positions, offering excellent stability under standard reaction conditions. The compound exhibits high compatibility with diverse nucleophiles, including amines and thiols, and is readily purified by crystallization or flash chromatography—making it ideal for scalable synthesis of kinase inhibitors and other bioactive molecules.
