organic compound found in many household prod- ucts. It is commonly used in the manufacture of plastics, textiles, coatings, rubber-based industrial cements, printing inks, bonding agents, and magnetic tapes. The compound is an effective and common sol- vent that contributes to its main application as a low- boiling solvent for nitrocellulose, acrylic, and vinyl surface coatings.
