The study is dedicated to the development of novel techniques for the synthesis and analysis of supramolecular complex of 1-methylcyclopropene and cucurbit[6]uril, with a view of further development of new agricultural products, e.g. Oberigpro and others, for fruit and vegetable treatment. Synthetic procedures were significantly improved at all stages allowing time and feedstock saving, as well as process efficacy and ecological aspect enhancement. Robust analytical procedure for 1-methylcyclopropene assaying was developed with the use of high performance liquid chromatography and chemical derivatization of 1-methylcyclopropene. Moreover, the release of the active compound from the complex was considerably increased, and high complex stability under various conditions was shown. In general, the study performed allowed making Oberigpro one of the most effective products for practical application among the existing analogs, and paved the way for further development of new agricultural products with controlled action.
