高釕酸四正丙基銨（縮寫TPAP或TPAPR）是一種化合物，化學式為N(C₃H₇)₄RuO₄，有時被稱作Ley–Griffith試劑，用於有機合成。它是離子化合物，氧化性很強，但是其單電子還原的衍生物是用於將醇轉化為醛的溫和氧化劑。^[1]該氧化劑也可用於將伯醇直接氧化至羧酸。使用較高的催化劑負載量，較大量的助氧化劑，以及兩當量的水。在這種情況下，醛與水反應形成偕二醇水合物，然後再次被氧化。^[2]

氧化反應產生水，可以通過分子篩去除。TPAP價格昂貴，但它可以以催化量使用。通過加入化學計量比的助氧化劑（如N-甲基嗎啉-N-氧化物）^[3]或氧氣^[4]來維持催化循環。

醇至醛的氧化反應，所需TPAP（0.06 eq）、N-甲基嗎啉-N-氧化物（1.7 eq）以及二氯甲烷中的分子篩^[5]
