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

(S)-3-((tert-Butoxycarbonyl)amino)-3-(m-tolyl)propanoic acid is a chiral building block featuring a protected amino group and a meta-tolyl substituent. This configuration enables selective incorporation into peptide architectures, where the tert-butyl carbamate moiety offers stability and convenient deprotection under mild acidic conditions. The molecule’s steric and electronic profile supports efficient coupling reactions in synthetic sequences.

Application

(S)-3-((tert-Butoxycarbonyl)amino)-3-(m-tolyl)propanoic acid serves as a stereochemically defined building block for peptidomimetics and bioactive heterocycles. The Boc-protected amine enables straightforward deprotection under mild acidic conditions, while the meta-tolyl group provides steric and electronic modulation. Its bench-stable nature and compatibility with standard coupling protocols facilitate efficient incorporation into complex molecular architectures.
