    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

Acid-PEG5-C2-Boc features a C2 spacer linking a terminal carboxylic acid to a PEG5 chain, terminated with a Boc group. This design enables site-specific conjugation in aqueous media while maintaining stability under standard conditions. The Boc moiety provides protection for amine functionalities during synthesis and purification workflows.

Application

Acid-PEG5-C2-Boc serves as a versatile, bench-stable linker for peptide and oligonucleotide conjugation, enabling efficient attachment of carboxylic acid-containing molecules via amide bond formation. The PEG5 spacer provides enhanced solubility and reduced aggregation, while the Boc group offers reliable protection of primary amines during synthesis. This reagent facilitates orthogonal functionalization in multi-step synthetic sequences and is compatible with standard coupling protocols used in medicinal chemistry and bioconjugation workflows.
