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+
Inaccessible (Haz class 6.1 or 9), International	$108.00+
Accessible (Haz class 3, 4, 5 or 8), International	$238.00+

Description

(1H-Pyrazol-1-yl)methanol features a pyrazole ring tethered to a reactive hydroxymethyl group, enabling direct functionalization in synthetic transformations. This bench-stable scaffold integrates readily into heterocyclic architectures and serves as a key intermediate in medicinal chemistry campaigns targeting kinase inhibitors and bioactive nitrogen-containing compounds.

Application

(1H-Pyrazol-1-yl)methanol serves as a versatile building block in medicinal chemistry, enabling the introduction of a polar, hydrogen-bonding pyrazole moiety adjacent to a reactive aldehyde. It functions effectively in nucleophilic additions, reductive aminations, and as a precursor for heterocyclic ring elaboration. The compound exhibits good bench stability and facilitates straightforward purification, making it suitable for high-throughput synthesis and process development workflows.
