    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

Azido-PEG1-CH2CO2H features a reactive azide group linked to a single ethylene glycol unit, terminating in a carboxylic acid. This bifunctional scaffold enables site-specific conjugation via click chemistry and facilitates purification or immobilization through the acidic moiety. Designed for bioconjugation workflows requiring short spacer length and high solubility.

Application

Azido-PEG1-CH₂CO₂H serves as a versatile bifunctional building block for bioconjugation and peptide synthesis, combining the reactivity of an azide group with the solubility and stability of a short PEG spacer. The carboxylic acid functionality enables direct coupling to amines via standard amide bond formation, while the terminal azide facilitates efficient copper-catalyzed or strain-promoted cycloaddition reactions. Ideal for modular construction of functionalized peptides, probes, and conjugates, it offers excellent bench stability and compatibility with common purification methods.
