The left ventricular ejection fraction (LVEF) test rate is increasingly used as a quality of care indicator for pa-. tients with heart failure. Our study produced benchmark LVEF test rates in a Medicare fee-for-service.
Toluene is a very good solvent because, unlike water, it can dissolve many organic compounds. In many commercial products, toluene is used as a solvent that is present in paint thinners, nail polish remover, glues, and correction fluid. Toluene has many uses in different industries.
Toluidine is the other name of methylaniline or aminotoluene. There are three structural isomers, ortho-TOLUIDINE, meta-TOLUIDINE, and para-TOLUIDINE.-toluidine and m-toluidine are clear to pale yellow, oily liquid. But P-toluidine solidifies to an off-white crystalline solid at about 43 C as it has more symmetrical structure. They are sensitive to air and light and tend to darken on storage.
