Weißer Stein (Eifel) 2007 the University of Liège executed measurements and found a height of 692 m (TAW, Belgian standard). The altitude meter of Google Earth caused some doubt about Signal de Botrange (694 m TAW) as Belgium's highest point because its vertical reference EGM96 deviates a couple of meters from the German Normalnull and the Belgian TAW, thereby suggesting an altitude of 701 m for the Weißer Stein. An accurate control by the Belgian National Geographic Institute in 2010 showed the Weißer Stein to be at maximum 693.3 m TAW (=691 m NN), with which it differs by less than 1 m
AM-694 mapping the distribution of CB receptors in the body. AM-694 metabolism differs only slightly from that of JWH-018. AM-694 "N"-dealkylation produces fluoropentane instead of pentane (or plain alkanes in general). It has been speculated that the fluoropentane might function as an alkylating agent or is further metabolized into toxic fluoroacetic acid. This is not true since fluoroalkanes do not act as alkylating agents under normal conditions and uneven fluoroalkane chains metabolize into substantially less toxic fluoropropanoic acid. AM-694 AM-694 (1-(5-fluoropentyl)-3-(2-iodobenzoyl)indole) is a drug that acts as a potent and selective agonist for the cannabinoid receptor CB. It is used in
