    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

Br-PEG4-C2-Boc features a bromide handle flanked by a PEG4 spacer and a C2 linker, terminating in a Boc-protected amine. This bifunctional construct enables site-specific conjugation under mild conditions while maintaining stability during storage and handling.

Application

Br-PEG4-C2-Boc serves as a versatile bifunctional building block for peptide and oligonucleotide conjugation, enabling site-specific attachment via bromide displacement. The PEG4 spacer provides enhanced solubility and reduced aggregation, while the C2 linker offers flexibility for downstream deprotection. The Boc group ensures stability during synthesis and facilitates selective removal under mild acidic conditions, making it ideal for iterative coupling workflows in medicinal chemistry and chemical biology applications.
