1-Pyrenebutanol (CAS 67000-89-9) is a pyrene-based fluorescent alcohol available from Sarchem Labs for polymer chemistry and materials science. It joins the four-ring pyrene chromophore to a four-carbon chain capped with a hydroxyl group, giving both strong fluorescence and a reactive -OH handle. Useful as a ring-opening polymerization initiator and as a fluorescent polymer/nanoparticle tag. Every batch ships with a COA and SDS.

Product Description

What is 1-Pyrenebutanol?

1-Pyrenebutanol is a pyrene-based aromatic alcohol in which a four-carbon hydroxyl-terminated chain is attached to pyrene’s 1-position (C20H18O, CAS 67000-89-9). It’s isolated as a white to light-yellow solid, melting 80–83°C. The pyrene ring fluoresces strongly under UV, making it a spectroscopic label more than a bulk structural material.

Uses of 1-Pyrenebutanol

Its hydroxyl group initiates ring-opening polymerization of cyclic esters, producing polylactide/polycaprolactone chains with a built-in fluorescent pyrene end-group — useful for tracking chain formation or nanoparticle assembly by fluorescence. Also used as an interfacial agent in polycarbonate/carbon-nanotube composites and as a fluorescent enzyme-assay substrate.
