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 building block features a (S)-configured backbone with a para-tert-butoxyphenyl group and a tert-butoxycarbonyl-methylamino side chain, enabling direct incorporation into peptide scaffolds. The sterically protected functionality ensures stability during synthesis and purification under standard conditions.

Application

(S)-3-(4-(tert-Butoxy)phenyl)-2-((tert-butoxycarbonyl)(methyl)amino)propanoic acid serves as a versatile chiral building block for medicinal chemistry, enabling efficient access to biologically relevant scaffolds. The protected amine and carboxylic acid functionalities offer orthogonal reactivity, facilitating peptide coupling and selective deprotection sequences. Bench-stable and readily purified by standard chromatography, it functions effectively in multi-step syntheses requiring stereocontrol and functional group compatibility.
