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-Chloro-3-iodopyrazolo[1,5-a]pyrimidine features a fused heterocyclic core with complementary halogen handles: a chlorine at C5 and an iodine at C3. This arrangement enables selective cross-coupling reactions in late-stage functionalization, particularly in the synthesis of complex pyrazolopyrimidine-based pharmaceuticals and agrochemicals. The electron-deficient scaffold supports efficient palladium-catalyzed transformations under mild conditions.

Application

5-Chloro-3-iodopyrazolo[1,5-a]pyrimidine serves as a versatile heterocyclic building block for late-stage functionalization in medicinal chemistry. The orthogonal reactivity of chlorine and iodine enables sequential cross-coupling transformations under palladium catalysis, facilitating the construction of complex pyrazolopyrimidine scaffolds. Bench-stable and compatible with standard purification methods, it functions reliably in Suzuki-Miyaura, Stille, and Buchwald-Hartwig reactions, supporting efficient diversification of bioactive molecules.
