    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

2-(Tritylthio)ethanamine features a trityl-protected thiol group that enables selective conjugation in peptide synthesis. This robust protecting group resists premature oxidation and cleaves cleanly under mild acidic conditions, delivering free thiols for downstream functionalization. The molecule’s hydrophobic trityl moiety enhances solubility in organic media while maintaining stability during standard coupling protocols.

Application

2-(Tritylthio)ethanamine serves as a robust sulfur-protecting group for thiols, enabling selective functionalization in complex molecule synthesis. The trityl (triphenylmethyl) moiety provides excellent steric shielding and facilitates easy removal under mild acidic conditions. Its stability under a range of reaction conditions—oxidative, reductive, and nucleophilic—makes it ideal for multi-step sequences, particularly in peptide and oligonucleotide derivatization.
