Zusammenfassung
Aus Cuticularwachs geschlechtsreifer Weibchen vonBlattella germanica (L.) wurde 3,11-Dimethyl-2-nonacosanon isoliert, das erwachsene Männchen der Art zum Balzverhalten anregt, wenn sie es mit ihren Antennen berühren.

Mass spectrum was measured with a Hitachi RMS-4 mass spectrometer attached with a Hitachi K-53 gas chromatograph (5% OV-17).
In spite of the presence of 2 possible asymmetric carbons, no optical rotation was observed inn-hexane solution (c=1.85) in the range 240–600 nm.
