3,4-Dihydroxyphenylacetic Acid, better known by its abbreviation DOPAC, is a phenylacetic acid with a catechol group (two adjacent hydroxyl groups) on its aromatic ring. In biology, DOPAC is known as one of the main metabolites of dopamine, so it is widely used in neurochemistry and pharmacology laboratories. In the chemistry laboratory, the compound also serves as a non-heterocyclic building block for synthesising catechol derivatives, esters, amides and other polyphenolic compounds built on a phenylacetic framework. This TCI product (catalogue D1283, CAS 102-32-9) supplies the compound for both analytical and synthetic work.

What sets DOPAC apart is its structure. The catechol group is redox-active and oxidises easily, so electrochemical detectors can pick up the compound with very high sensitivity. The carboxylic acid group adds a convenient reactive site for derivatisation. With both functions in one molecule, DOPAC works as an analytical standard as well as a synthetic starting material. Because it oxidises so readily, the quality of the starting material has a large effect on how accurate the results are. A well-characterised TCI product gives researchers a dependable reference point for quantitative measurements and for multi-step synthesis.

In Indonesia, DOPAC is relevant to pharmacology and neuroscience laboratories in faculties of medicine, pharmacy and biology that study dopamine metabolism and related neurochemical pathways. Organic and medicinal chemistry groups can also use it as a starting material when building catechol-containing compounds and polyphenol analogues. University research laboratories, analytical service units and teaching laboratories can all source this TCI-branded material through AMI Scientific for reproducible research and method development.

DOPAC contains a catechol group that oxidises easily, so keep exposure to air, light and moisture to a minimum. Store the product in its original, tightly closed container in a cool, dry, well-ventilated place, following the storage conditions on the TCI label and safety data sheet. Reseal the container promptly after each use, and consider dispensing only the amount needed so the bulk material stays intact. Handle the compound with standard laboratory protective equipment, including gloves, safety glasses and a lab coat. Avoid creating or breathing in dust, and work in a fume hood or well-ventilated area. Keep it away from strong oxidising agents, and dispose of residues according to local regulations and institutional procedures.
