    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

Benzyltriethoxysilane serves as a versatile organosilicon reagent for surface functionalization and sol-gel processing. This moisture-tolerant compound features a benzyl group that integrates into hybrid organic-inorganic networks, enhancing compatibility with polymer matrices. The ethoxy groups hydrolyze readily under mild conditions, enabling covalent anchoring to oxide surfaces.

Application

Benzyltriethoxysilane serves as a reliable silyl protecting group for alcohols and amines, offering excellent bench stability and compatibility with standard deprotection protocols. It facilitates efficient Si–O bond formation under mild conditions and enables orthogonal protection in complex molecule synthesis. The triethoxysilyl moiety provides high reactivity in Staudinger-type coupling reactions and supports robust functional group tolerance across diverse synthetic sequences.
