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

Boc-S-3-amino-4-(4-methoxyphenyl)-butyric acid is a bench-stable, moisture-tolerant amino acid derivative featuring a para-methoxy-substituted phenyl group and a tert-butoxycarbonyl-protected amine. This configuration enables direct incorporation into peptide synthesis workflows without pre-activation, delivering enhanced solubility and compatibility with standard coupling protocols.

Application

Boc-S-3-amino-4-(4-methoxyphenyl)-butyric acid serves as a versatile building block for the synthesis of biologically active compounds, enabling efficient incorporation of the 4-methoxyphenyl group into peptide and non-peptidic scaffolds. The Boc-protected amine facilitates straightforward handling and orthogonal deprotection under mild acidic conditions, while the carboxylic acid function supports standard coupling reactions. Its stability and compatibility with diverse reaction conditions make it suitable for medicinal chemistry campaigns targeting CNS and metabolic disease therapeutics.
