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+

Description

3-Bromo-2-chloro-5-nitro-6-picoline features a densely functionalized pyridine core with orthogonal halogen and nitro substituents. This electron-deficient heterocycle enables selective cross-coupling reactions under palladium catalysis, serving as a key intermediate in the synthesis of advanced pharmaceutical scaffolds and bioactive nitrogen-containing compounds.

Application

3-Bromo-2-chloro-5-nitro-6-picoline serves as a versatile building block for heterocyclic synthesis, enabling sequential functionalization via cross-coupling and nucleophilic substitution. Its complementary halogenation pattern facilitates selective transformations under palladium-catalyzed conditions, while the nitro group provides a handle for reduction and subsequent cyclization. Bench-stable and compatible with standard purification protocols, it supports efficient access to complex nitrogen-containing scaffolds relevant in medicinal chemistry and agrochemical development.
