PnB，Propylene glycol butyl ether，CAS 5131-66-8，Glycol Ether Solvents

Product Name: PnB
Also Known As: Propylene glycol butyl ether / 1-Butoxy-2-propanol / PGMBE
CAS No.: 5131-66-8
Molecular Formula: C₇H₁₆O₂

Product Introduction

Propylene glycol butyl ether, chemically known as 1-(or 2-) propylene glycol monobutyl ether, is a significant alcohol ether solvent. Its chemical formula is C₇H₁₆O₂, with common isomers including Propylene glycol n-butyl ether (PnB) and Propylene glycol t-butyl ether (PtB), which exhibit slightly different properties. Relevant CAS numbers are typically 5131-66-8 for PnB and 57018-52-7 for PtB.

Compared to ethylene glycol ether solvents (e.g., ethylene glycol butyl ether), propylene glycol ethers (e.g., propylene glycol butyl ether) are significantly less toxic, offering a safer and more environmentally friendly profile, making them ideal substitutes.
