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

Description

4-Amino-3-methylbenzoic acid features a strategically positioned amino group and methyl substituent on the aromatic ring, enabling precise tuning of electronic properties and solubility. This ortho-substituted benzoic acid derivative serves as a key intermediate in the synthesis of bioactive compounds and functional materials, offering enhanced reactivity in coupling and derivatization processes under standard conditions.

Application

4-Amino-3-methylbenzoic acid serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling access to diverse heterocyclic scaffolds through standard coupling and cyclization protocols. Its ortho-substituted aryl functionality provides enhanced metabolic stability and tunable solubility, while the amino and carboxylic acid groups offer orthogonal reactivity for peptide coupling, amide formation, and derivatization. Bench-stable and readily purified by recrystallization, it functions reliably in multi-step syntheses requiring functional group compatibility and structural precision.
