摘要
<正> 在合成抗高血压新药研究中。
N-(4-Chlorobcnzoyl)-dicyclohexanylurea (Ⅳ), the by-product in synthesis of antihypertensive compound (MX-2), was identificd by FTMS/SCI. This mcthod provided the molecular weight and structure information as well. In the wide mass range and routine determination, the pseudomolecular ion peak (M+1) was measured as 363.179970 amu, the error was only 9.4 ppm, and gave the elemental Composition C_(20)H_(28)O_2N_2Cl.
