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

This tetrakis(benzyloxy)hexaldehyde features a stereochemically defined backbone with benzyl-protected hydroxyl groups, enabling reliable glycosylation intermediacy. The aldehyde functionality at C5 provides a reactive handle for coupling reactions under standard conditions. Bench-stable and moisture-tolerant, it streamlines synthesis of complex oligosaccharides and glycoconjugates.

Application

(2R,3S,4S,5R)-2,3,4,6-Tetrakis(benzyloxy)-5-hydroxyhexanal serves as a key chiral building block in carbohydrate chemistry, enabling efficient access to complex oligosaccharide scaffolds. Its well-defined stereochemistry and multiple protected hydroxyl groups facilitate selective functionalization and glycosylation reactions. The benzyl protecting groups offer excellent stability under a range of reaction conditions and can be removed cleanly via catalytic hydrogenolysis, simplifying downstream processing. This compound functions reliably in standard solution-phase synthesis workflows for natural product and glycoconjugate assembly.
