TCI M0248 7-Methylbenz[a]anthracene is a polycyclic aromatic hydrocarbon (PAH) built from four fused aromatic rings, carrying a methyl group at the seventh position. The compound is supplied in a small 100 mg pack, a size that reflects how it is actually used: as an analytical reference compound and a specialised research material rather than as a routine synthesis reagent. In the laboratory it serves primarily as a reference standard for PAH analysis in environmental chemistry, forensic science, and toxicology research, and as a model compound in studies of how aromatic hydrocarbons interact with biological systems and materials.

The property that defines its usefulness is its extended conjugated pi-electron system. The four-ring structure gives rise to highly characteristic ultraviolet absorption spectra and fluorescence behaviour, which means the compound can be detected at low concentrations using fluorescence detectors on HPLC as well as by mass spectrometry coupled to gas chromatography. The methyl group at position seven shifts retention time and alters fragmentation patterns relative to the parent hydrocarbon, so the compound plays an important role in confirming the separation and identification of substituted PAHs within complex mixtures where isomers must be distinguished from one another.

In Indonesian laboratories, this material is typically held by environmental monitoring facilities, forensic units, university research groups, and toxicology laboratories that carry out PAH profiling. Because it functions as a calibration and identification standard rather than a bulk input, a single 100 mg pack generally supports an extended programme of analytical work. It is normally handled by trained analysts as part of a defined method, with the sample drawn in small quantities for standard preparation.

Product code: M0248

Keep the container tightly closed in a cool, dry, well-ventilated place, away from light, heat, and sources of ignition, and follow the storage conditions stated by the manufacturer on the label and safety data sheet. The original supplier container, or an amber glass vial with a chemically resistant closure, is suitable for storage and for any working aliquots. As a polycyclic aromatic hydrocarbon intended for research and analytical use, it should be handled only by trained personnel, weighed and transferred inside a fume hood, and used with gloves, safety glasses, and a laboratory coat. Avoid generating dust, avoid all contact with skin and eyes, and dispose of residues and contaminated consumables as chemical waste in line with institutional procedures.
