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

(1-Methyl-1H-pyrazol-4-yl)methanol features a pyrazole core with a methyl substituent at the 1-position and a primary alcohol at the 4-position, delivering a polar, bench-stable scaffold ideal for bioconjugation and medicinal chemistry. The molecule integrates readily into drug discovery workflows, offering enhanced solubility and reactivity in functionalization reactions.

Application

(1-Methyl-1H-pyrazol-4-yl)methanol serves as a versatile building block in medicinal chemistry, enabling efficient access to pyrazole-containing scaffolds. Its benzylic alcohol functionality facilitates direct oxidation to the carboxaldehyde or ester, and it participates reliably in coupling reactions with amines, alcohols, and nucleophiles under standard conditions. The molecule exhibits good bench stability and is compatible with common protecting group strategies, making it well-suited for multi-step synthesis workflows.
