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

Pyridazin-4-ylmethanol features a pyridazinone core with a primary alcohol handle, enabling direct functionalization in synthetic sequences. This bench-stable scaffold integrates readily into bioactive molecule design, particularly where nitrogen-rich heterocycles enhance target affinity. The hydroxymethyl group facilitates derivatization under mild conditions, supporting efficient access to diverse analogs.

Application

Pyridazin-4-ylmethanol serves as a versatile building block in medicinal chemistry, enabling efficient access to heterocyclic scaffolds through straightforward functionalization. Its benzylic alcohol functionality facilitates oxidation to the aldehyde or carboxylic acid, and it participates reliably in coupling reactions with amines, halides, and boronic acids. The pyridazinone core exhibits favorable metabolic stability and hydrogen-bonding capacity, making it suitable for target-directed synthesis. Bench-stable and readily purified by silica gel chromatography, it functions effectively in standard synthetic workflows.
