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

Histamine inhibits the synthesis of IL-2 and γ-IFN in peripheral blood mononuclear cells and lipopolysaccharide-induced synthesis of TNF-α in monocytes via H2 receptor activation. It is a powerful stimulant of gastric secretion, a constrictor of bronchial smooth muscle, a vasodilator, and also a centrally acting neurotransmitter.

Application

1-Bromo-4-methoxybutane serves as a versatile bifunctional building block in synthetic organic chemistry, enabling efficient construction of ether-linked chains and heterocyclic systems. Its terminal bromide facilitates nucleophilic substitution reactions, while the methoxy group provides stability and compatibility with diverse reaction conditions. This compound functions reliably in coupling protocols, ring-forming transformations, and as a precursor to bioactive scaffolds, offering predictable reactivity and straightforward purification for bench-scale applications.
