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+

Description

This chiral dipeptide scaffold features a (R)-di-tert-butyl ester configuration paired with an (S)-4-amino-5-tert-butoxy-5-oxopentanamido moiety, delivering enhanced stability and solubility in organic media. The protected amine and ester functionalities enable direct incorporation into peptide synthesis workflows without side-reaction interference.

Application

(R)-di-tert-butyl 2-((S)-4-amino-5-tert-butoxy-5-oxopentanamido)pentanedioate serves as a chiral building block for the synthesis of bioactive peptides and heterocyclic scaffolds. Its tert-butyl ester groups offer bench stability and ease of deprotection, while the amino and carbonyl functionalities enable selective coupling reactions. The molecule functions effectively in standard amide bond formation protocols and supports orthogonal protection strategies in complex molecule assembly.
