TCI D4080, CAS 5409-31-4, is 3,4-Diethoxybenzoic Acid, a benzoic acid bearing two ethoxy groups at the 3- and 4-positions and classified as a non-heterocyclic building block. The compound presents two functionalities within a single molecule: a carboxylic acid group that serves as the primary reaction handle for ester and amide formation, and an electron-rich aromatic ring resulting from the pair of alkoxy substituents. This combination makes it a frequent starting scaffold when researchers construct molecules with the veratrole substitution pattern commonly encountered across a wide range of active compounds.

The property that makes this material attractive is the stability of the ethyl ether groups, which are not readily cleaved under common reaction conditions and therefore do not require the additional protection steps that a free phenol group would demand. The carboxyl group can be activated straightforwardly into an acyl chloride, an active ester, or a mixed anhydride, and then coupled with amines using standard coupling reagents. As a solid, the compound is convenient to weigh accurately, is easily purified by recrystallization, and remains relatively stable under ordinary storage conditions.

Its moderate polarity also simplifies reaction monitoring by thin-layer chromatography and subsequent purification work. In Indonesian laboratories, these characteristics suit the practical realities of university research groups, government research institutes, and industrial R&D units, where straightforward handling and predictable behavior on the bench matter. Supplied by AMI Scientific, the material fits synthetic chemistry work in which a dependable, well-defined aromatic building block is required as the entry point to a longer synthetic sequence.

  • Amide bond formation: the carboxylic acid couples with primary and secondary amines using standard coupling reagents, making it a direct entry point to substituted benzamide targets.
  • Esterification chemistry: the carboxyl group is readily converted into esters, allowing researchers to prepare protected intermediates or modify solubility for the next step in a sequence.
  • Veratrole-pattern scaffold construction: the 3,4-dialkoxy arrangement reproduces a substitution motif found in many active compounds, giving synthetic chemists a ready-made aromatic core.
  • Acyl chloride and mixed anhydride preparation: the acid activates cleanly into more reactive acyl species, supporting acylation reactions that require a strongly electrophilic carbonyl centre.
  • Method development and reaction monitoring: its moderate polarity gives clear thin-layer chromatography behaviour, which helps chemists track conversion and optimize purification conditions reliably.

Store the container tightly closed in a cool, dry place, away from direct sunlight, moisture, and sources of ignition or excessive heat. The original manufacturer container is the most suitable primary packaging; if transferring material, use clean, dry, chemically compatible glass or plastic vessels that are clearly labelled with the compound name and CAS number. Handle the solid in a well-ventilated area or fume hood to avoid dust inhalation, and wear standard personal protective equipment including safety goggles, gloves, and a laboratory coat. Avoid contact with skin and eyes, keep the material away from incompatible substances such as strong bases and strong oxidizing agents, and use a clean, dry spatula each time to prevent contamination of the bulk material. Always consult the manufacturer safety data sheet before use and dispose of residues according to applicable laboratory waste procedures.
