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+

Description

1-(Methoxymethyl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole features a boronate ester group enabling reliable Suzuki-Miyaura cross-coupling reactions. The methoxymethyl substituent enhances solubility and stability under standard conditions. This compound serves as a robust building block for constructing complex heterocyclic architectures in medicinal chemistry and materials science.

Application

1-(Methoxymethyl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole serves as a versatile boronate building block for Suzuki-Miyaura cross-coupling reactions. The pyrazole core provides metabolic stability and hydrogen-bonding capacity, while the methoxymethyl group offers orthogonal protection and mild deprotection conditions. The pinacol boronate moiety enables high functional group tolerance, excellent bench stability, and compatibility with diverse reaction conditions, facilitating efficient assembly of complex heterocyclic scaffolds in medicinal chemistry and materials science applications.
