Pyrene

Pyrene (CAS 129-00-0), also known as Benzo[def]phenanthrene, is a polycyclic aromatic hydrocarbon sourced primarily as a byproduct of coal tar processing. It is used commercially as a fluorescent dye intermediate and as a reference compound in analytical and colorant chemistry.

In textile and leather dyeing, pyrene serves as a precursor in the synthesis of vat dyes and fluorescent colorants that require high wash and light fastness. Coatings and printing ink formulators use pyrene-derived pigments to achieve intense fluorescent effects.

These specialty inks and UV-reactive surface coatings are essential for high-performance industrial applications. In adhesives and sealant formulations, pyrene-based compounds contribute to UV-traceable systems used for quality inspection and bond verification.

These systems are critical for industrial assembly where precision is required. Paper and packaging manufacturers incorporate pyrene-derived fluorescent agents into security printing applications where optical detection is required for authentication.

Pyrene is supplied as a pale yellow to off-white crystalline powder or as flakes. Technical grade material is the standard commercial form, typically available at purities of 98% and above for various industrial manufacturing processes.

Higher-purity grades are available for use as analytical reference standards in laboratory and quality control settings. Our material meets rigorous internal specifications to ensure consistent performance across all chemical synthesis and dyeing applications.
