Analytes - p-xylene
p-xylene: CAS No. 106-42-3, C8H10, molecular weight 106.16, boiling point 138.4°C, density 0.86gm/mL, vapor pressure 8.8mm Hg at 25°C, flash point 25°C, autoignition temperature 528°C, slightly water soluble is a colorless liquid used in the synthesis of terephthalic acid for polyester resins and fibers such as Dacron, Mylar, and Terylene; in pharmaceutical synthesis and in insecticides. It is most frequently measured in water, air and soil to comply with environmental regulations. Due to its volatility, it is most often measured using GC/PID, FID and GC/MS methods specified by regulatory agencies like the U.S. EPA.
