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

2-Bromo-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-carbaldehyde features a brominated pyrrolopyrazine core with a trimethylsilyl-protected ether side chain and an aldehyde handle. This bifunctional scaffold enables direct coupling in cross-coupling or conjugation workflows, leveraging the silyl group for orthogonal protection and the aldehyde for downstream derivatization under mild conditions.

Application

2-Bromo-5-((2-(trimethylsilyl)ethoxy)methyl)-5H-pyrrolo[2,3-b]pyrazine-7-carbaldehyde serves as a versatile building block for the synthesis of pyrrolopyrazine-based heterocycles. The bromo and aldehyde functionalities enable sequential cross-coupling and functionalization reactions, while the trimethylsilyl-protected ether offers stability and orthogonal deprotection. Its bench-stable nature and compatibility with standard Pd-catalyzed transformations facilitate efficient construction of complex scaffolds in medicinal chemistry and materials research.
