    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

(Chloromethyl)triethoxysilane features a reactive chloromethyl group tethered to a triethoxysilyl moiety, enabling direct grafting onto siliceous surfaces. This dual functionality facilitates robust covalent attachment in surface modification protocols. The molecule exhibits excellent stability under standard conditions and undergoes controlled hydrolysis to yield active silanol species for subsequent condensation reactions.

Application

(Chloromethyl)triethoxysilane serves as a versatile silyl-protected chloromethyl building block, enabling selective functionalization in complex molecule synthesis. Its stable triethoxysilyl group facilitates easy handling and purification, while the reactive chloromethyl moiety participates reliably in nucleophilic substitution reactions. This reagent functions effectively in the construction of silicon-directed synthetic intermediates and provides orthogonal protection in multi-step sequences, making it valuable for applications in medicinal chemistry and materials science.
