Description
1,4-Chrysenequinone (TCI C2214) is a quinone derivative of the chrysene skeleton, a four-ring polycyclic aromatic hydrocarbon. The compound belongs to the oxy-PAH group, the oxidation products of polycyclic aromatic hydrocarbons that are commonly encountered as the result of incomplete combustion as well as metabolites within biological systems. In the laboratory, its role is primarily that of a reference material and test substance in environmental research, toxicology, and analytical chemistry, since the presence of compounds in this class serves as an important indicator in studies of air and particulate pollution.
The property that makes this compound a preferred choice is the conjugated quinone structure carried on an extended aromatic framework. The quinone group is electrophilic and capable of undergoing redox cycling, so the compound is frequently adopted as a model in studies of reactive oxygen species formation and of interactions with biological thiols. Its four-ring aromatic system gives a characteristic ultraviolet-visible absorption and dependable chromatographic behaviour, which makes identification straightforward with diode array detectors as well as with mass spectrometry. As a coloured solid, the compound also provides a simple visual indication of its condition.
In Indonesian laboratories, TCI C2214 is typically used in university and government research settings concerned with air quality and particulate matter, where oxy-PAH species are tracked as markers of incomplete combustion. It also finds a place in toxicology groups examining oxidative stress mechanisms, and in analytical chemistry laboratories that need a well-characterised reference substance when developing or validating chromatographic and spectrometric methods for polycyclic aromatic compounds.
Laboratory Applications
Environmental monitoring of air and particulate matter, where this oxy-PAH acts as a reference marker for tracing products of incomplete combustion in collected samples.
Analytical method development and validation, since its distinctive ultraviolet-visible absorption and reliable chromatographic behaviour give a dependable reference peak for diode array and mass spectrometric detection.
Toxicology research on oxidative stress, where the electrophilic quinone group and its capacity for redox cycling make the compound a useful model for reactive oxygen species formation.
Studies of interactions with biological thiols, because the electrophilic character of the quinone moiety allows researchers to model how such species react within biological systems.
Reference and test substance work in PAH metabolism studies, given that oxy-PAH compounds of this type arise as metabolites in biological systems and require authentic standards for comparison.

Handling and Storage
Store the compound in its original tightly closed container, kept in a cool, dry place and protected from light, since the conjugated quinone structure is sensitive to prolonged light exposure. Amber glass vials or opaque containers are suitable for storage and for the preparation of working solutions. As with all polycyclic aromatic compounds, handle the material in a fume hood, wear gloves, safety glasses, and a laboratory coat, and avoid the generation of dust when weighing. Prevent contact with skin and eyes, and dispose of residues and contaminated consumables through the laboratory's chemical waste procedure. Always consult the manufacturer's safety data sheet before use.
