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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+
Inaccessible (Haz class 6.1 or 9), International	$108.00+

Description

1,1,3,3-Tetramethyl-2-(3-(trimethoxysilyl)propyl)guanidine features a silyl-functionalized guanidine core enabling robust surface anchoring. The trimethoxysilyl group undergoes hydrolytic condensation to form stable siloxane linkages on silica and metal oxide surfaces. This reagent integrates seamlessly into hybrid organic-inorganic materials, delivering durable, moisture-tolerant coatings with enhanced adhesion properties.

Application

1,1,3,3-Tetramethyl-2-(3-(trimethoxysilyl)propyl)guanidine serves as a versatile silyl-protected guanidine building block, enabling efficient access to functionalized amidines and heterocyclic scaffolds. Its trimethoxysilyl group facilitates robust surface immobilization and silane coupling in materials chemistry, while the tetramethylguanidine core provides strong basicity and stability under standard synthetic conditions. The molecule exhibits excellent bench stability, simplifies purification, and tolerates diverse functional groups—making it ideal for applications in combinatorial synthesis, polymer modification, and the construction of bioactive heterocycles.
