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

High refractive index nanocrystal dispersions dramatically improve optical and mechanical properties to enable next-generation products. Incorporating ZrO2 significantly increases the refractive index of many commonly used polymers, while maintaining high transparency. This combination of key properties allows researchers to optimize optical efficiency and improve light extraction.

Application

N-(((9H-Fluoren-9-yl)methoxy)carbonyl)-N-methyl-S-trityl-L-cysteine serves as a protected cysteine building block for peptide synthesis, combining orthogonal protection of the thiol (trityl) and amine (Fmoc) functionalities. The Fmoc group enables mild base-mediated deprotection, while the trityl moiety provides robust protection against oxidation and side reactions. Its bench-stable solid form facilitates handling, purification, and incorporation into complex sequences via standard coupling protocols.
