We report experimental results of electrical resistivity, de Haas-van Alphen effect, specific heat and thermal expansion of U[Pd.sub.2][Al.sub.3]. The nominal composition is denoted by the formula of U[Pd.sub.2 + x][Al.sub.3 + y]. Samples with the composition of U[Pd.sub.2][Al.sub.3.03] and U[Pd.sub.2.02][Al.sub.3.03] reveal de Haas-van Alphen oscillations of the magnetic susceptibility. An anomaly is observed in the superconducting phase in the temperature dependence of the specific heat and thermal expansion of U[Pd.sub.2][Al.sub.3.03]. The relation between the sample quality and the appearance of the anomaly is discussed.
