    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

Benzyl 2-(2-hydroxyethoxy)ethylcarbaMate features a hydroxylated ethylene spacer that enhances solubility and facilitates conjugation in bioconjugation workflows. The carbamate linkage provides stability under physiological conditions while enabling controlled release in targeted applications. This compound serves as a robust linker for peptide and oligonucleotide modifications.

Application

Benzyl 2-(2-hydroxyethoxy)ethylcarbamate serves as a versatile, bench-stable protecting group for primary amines, enabling selective functionalization in complex molecule synthesis. Its hydroxyether side chain enhances solubility and facilitates orthogonal deprotection under mild conditions. The carbamate functionality tolerates a broad range of reaction environments, including nucleophilic substitutions and metal-catalyzed couplings, making it ideal for iterative peptide and heterocycle assembly workflows.
