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.

FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

(S)-2-((tert-Butoxycarbonyl)amino)-5-ureidopentanoic acid features a chiral center at the α-position, bearing a tert-butoxycarbonyl-protected amine and a terminal ureido group. This bifunctional scaffold integrates a masked amine with a polar urea moiety, enabling selective conjugation in peptide synthesis and bioconjugation workflows under standard conditions.

Application

(S)-2-((tert-Butoxycarbonyl)amino)-5-ureidopentanoic acid serves as a versatile building block for the synthesis of peptide-based scaffolds and bioactive heterocycles. The Boc-protected amine and terminal ureido group enable sequential functionalization, offering compatibility with standard coupling protocols and orthogonal deprotection strategies. Its bench-stable nature and clean purification profile make it well-suited for iterative solid-phase and solution-phase syntheses in medicinal chemistry campaigns.
