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

tert-Butyl (4-nitrophenyl)carbamate delivers a robust, bench-stable protection for primary amines in synthetic workflows. The para-nitro group enhances electrophilic reactivity, while the tert-butyl carbamate moiety ensures facile deprotection under mild acidic conditions. This combination enables reliable nitrogen protection in complex molecule assembly.

Application

tert-Butyl (4-nitrophenyl)carbamate serves as a stable, bench-ready nitrogen protecting group for primary amines, enabling efficient introduction of the 4-nitrophenylcarbamate moiety in peptide and small-molecule synthesis. It facilitates orthogonal protection strategies due to its compatibility with diverse reaction conditions and allows for selective deprotection under mild acidic or hydrogenolytic conditions. The nitro group provides additional synthetic handles for downstream functionalization via reduction or electrophilic substitution.
