    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.

Description

3,5-Dimethyl-4-nitro-2-pyrrolecarboxaldehyde features a pyrrole core with electron-deficient nitro and aldehyde functionalities, enabling efficient coupling in heterocyclic synthesis. The dimethyl substitution enhances solubility and steric protection, while the para-nitro group facilitates conjugation and reactivity in transition-metal-catalyzed transformations. This bench-stable scaffold streamlines access to functionalized pyrrole derivatives for medicinal chemistry and materials applications.

Application

3,5-Dimethyl-4-nitro-2-pyrrolecarboxaldehyde serves as a versatile building block in heterocyclic synthesis, enabling efficient access to substituted pyrrole derivatives via standard condensation and coupling reactions. Its aldehyde functionality facilitates facile derivatization, while the nitro group enhances electrophilicity for nucleophilic addition and subsequent transformations. The dimethyl substitution provides steric and electronic modulation, improving stability and selectivity in multistep syntheses. This compound functions reliably in medicinal chemistry and materials science applications requiring robust, bench-stable intermediates with predictable reactivity.
