    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.

Description

Tetradecylphosphonic acid forms a self-assembled monolayer (SAM) to functionalize a variety of nanoparticles.TDPA can be used to cap copper nanoparticles to protect them from oxidation. It may also be used in the synthesis of cadmium sulfate (CdS) core, which can be used in the fabrication of cadmium selenium (CdSe)/CdS core quantum dots (QDs). It may also be coated on caesium lead bromide (CsPbBr3) perovskite quantum dots for the development of white light emitting diodes (wLED).

Application

L-Valine serves as a fundamental building block in peptide synthesis and metabolic pathway studies, offering excellent bench stability and high enantiomeric purity. Its branched aliphatic side chain enables selective incorporation into bioactive peptides and facilitates the construction of sterically hindered scaffolds. This amino acid functions reliably in standard coupling protocols and demonstrates broad functional group tolerance during synthetic transformations.
