01 /Applications

Organic Synthesis

Naphthalene serves as a fundamental building block in organic chemistry. Its aromatic structure makes it a versatile precursor for the synthesis of dyes, surfactants, and various other organic compounds.

Scintillation Counting

Due to its fluorescence properties, Naphthalene is suitable for use as a scintillator in radiation detection. It is incorporated into scintillation cocktails to detect and quantify radioactive isotopes.

Analytical Reagent

High-purity Naphthalene is utilised as an analytical reagent in chromatographic and spectroscopic methods. Its well-defined properties aid in calibration and as a reference standard.

Chemical Intermediate

It functions as a key intermediate in the production of phthalic anhydride, which in turn is used in the manufacture of plasticizers, resins, and dyes.
