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

Methyl stearate is one of the key fatty acid methyl ester (FAME) component of biodiesel fuel produced by the transesterification of triglyceride oil and a primary alcohol. It is reported to occur in the volatile oil of Rheum palmatum L rhizomes and Ziziphus spina-christi leaves.

Application

Levofloxacin Q-acid serves as a key synthetic intermediate in the construction of fluoroquinolone antibiotic scaffolds. Its carboxylic acid functionality enables direct coupling reactions with amines and heterocycles under standard amide bond-forming conditions. The molecule exhibits robust bench stability, facilitates straightforward purification via crystallization, and demonstrates compatibility with diverse functional groups present in complex medicinal chemistry workflows.
