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+
Accessible (Haz class 3, 4, 5 or 8), International	$238.00+

Description

tert-Butyl N-[2-(aminooxy)ethyl]carbamate features a labile carbamate group that enables selective protection of primary amines under mild conditions. The aminooxy functionality facilitates efficient oxime ligation, while the tert-butyl moiety ensures stability during storage and ease of removal via acidolysis. This compound serves as a key reagent in bioconjugation workflows and peptide modification strategies.

Application

tert-Butyl N-[2-(aminooxy)ethyl]carbamate serves as a stable, bench-friendly precursor for the introduction of aminooxy-functionalized side chains in synthetic workflows. It enables efficient conjugation strategies via oxime formation and functions as a key building block in the construction of bioconjugates and heterocyclic scaffolds. The tert-butyl group provides excellent stability and ease of removal under mild acidic conditions, facilitating straightforward purification and downstream functionalization.
