Description

Naphthalene, 1-(2-Phenylethynyl)- is a specialized organic compound featuring a naphthalene core substituted with a phenylethynyl group, making it a valuable building block in advanced chemical synthesis. This compound matters for its role as a key intermediate in the development of complex organic materials and functional molecules, where its rigid, conjugated structure is highly desirable. It is needed by research chemists and industrial manufacturers in the pharmaceutical, agrochemical, and material science sectors for creating novel compounds with tailored properties.

Application

• As a key synthetic intermediate in pharmaceutical research for the development of new active pharmaceutical ingredients (APIs).
• In the synthesis of organic electronic materials, such as organic light-emitting diodes (OLEDs) and semiconductors, due to its extended π-conjugation.
• As a precursor for advanced agrochemicals, including herbicides and plant growth regulators.
• For academic and industrial research in organic chemistry, particularly in cross-coupling and cyclization reactions.
• In the development of specialty dyes and pigments where specific light-absorption properties are required.
• As a building block for liquid crystals and other advanced functional materials.

Quality Control

Our Naphthalene, 1-(2-Phenylethynyl)- is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specific results for assay, related substances, and other critical parameters are available upon request, supporting your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). Keep container tightly sealed under an inert atmosphere such as nitrogen or argon to minimize degradation. Keep away from heat, sparks, and open flame.
