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

2-Hydroxy-5-methoxybenzaldehyde has acaricidal activity against Tyrophagus putrescentiae.2-Hydroxy-5-methoxybenzaldehyde was used to synthesize radiolabeling precursor desmethyl-PBR06. It was used to study electroantennogram response of the vine weevil (Otiorhynchus sulcatus F.) to a broad range of volatile plant compounds. It was used in the synthesis of tetradentate Schiff base compounds.

Application

2-Hydroxy-5-methoxybenzaldehyde serves as a versatile building block in medicinal chemistry and natural product synthesis, enabling efficient access to bioactive heterocycles. Its ortho-hydroxyl and methoxy groups provide complementary sites for electrophilic substitution, oxidation, or coupling reactions. The aldehyde functionality facilitates reductive amination, Ullmann-type couplings, and condensation reactions with amines or hydrazines. Bench-stable and readily purified by recrystallization, it functions reliably in multi-step syntheses of pharmaceutical intermediates and agrochemical scaffolds.
