Buy Propoxur-d3 Online Looking for where to buy Propoxur-d3 online? Propoxur-d3 is used as an internal standard for the quantification of propoxur (item no. 25628) by gas chromatography (GC) or liquid chromatography-mass spectrometry (LC-MS). Propoxur is a carbamate insecticide, an acetylcholinesterase inhibitor (IC50 = 4,3 µM), and an antagonist of nicotinic acetylcholine receptors containing the α4β4 subunit (IC50 = 165 µM for the rat receptor). 1,2 It is lethal to the German cockroach (B. germanica), with LD50 values ​​of 2,45, 4,73, and 1,06 µg per insect for newly emerged males and females and 4-week-old nymphs, respectively. Propoxur induces lactate dehydrogenase (LDH) release and inhibits gill cell growth in flounder (IC50 = 86,59 and 89,96 μg/ml, respectively) by inducing necrosis.3 It also induces yolk sac and pericardial edema in zebrafish embryos when used at concentrations of 100 and 200 μg/ml. Propoxur (8,3 mg/kg) inhibits blood and brain cholinesterase in rats, decreases wandering and rearing in an open field test, and increases the latency to escape from footshock following a sound stimulus in the two-way active avoidance box in rats.4 Formulations containing propoxur have been used for insect control in agriculture as well as in residential areas.
