Lufenuron standards

Lufenuron is an active ingredient in the group of chitin synthesis inhibitors used to control and prevent biting and sucking insects in dogs and cats. Lufenuron is also sold as an agricultural pesticide for use against lepidopterans, eriophid mites (Tuckerella sp.), and western flower thrips (Frankliniella occidentali)s. In addition it is an effective antifungal in plants. Residues of Lufenuron and its metabolites are found in environmental and water samples. For your investigations and...

Cypermethrin

Cypermethrin is a synthetic pyrethroid used as an insecticide in large-scale commercial agricultural applications as well as in consumer products for domestic purposes used to control ants and ticks. Cypermethrin is highly toxic to fish, bees and aquatic insects, according to the National Pesticide Information Center (NPIC). For your investigations and analysis, we can offer the following cypermethrin standards: [gview file="http://asca-berlin.de/files/wp-content/uploads/Cypermethrin-1.pdf"]...

Chlorothalonil metabolites

More recently, the so-called non-relevant metabolites (nrM) are increasingly becoming the focus of general consumer protection. They are often more polar and hydrophilic, and show high persistence than the active ingredients of pesticides itself. ASCA GmbH has successfully synthesized some metabolites of chlorothalonil and can offer these as internal standard. [gview file="http://asca-berlin.de/files/wp-content/uploads/Chlorothalonil-Metaboliten.pdf"] We look forward to your...

Beta-chlorolactic acid as internal standard

Beta-chlorolactic acid is a major intermediate of 3-monochloro-1,2-propanediol (MCPD) in mammalian species. 3-Monochloropropane-1,2-diol (3-MCPD) is a food contaminant known to display toxic effects. 3-MCPD is mainly produced in the refining of vegetable fats and oils, so in the heat treatments to remove undesired substances. For your investigations and analysis, we can offer the ß-Chlorolactic acid as isotope-labelled internal standard. Contact us for enquires about these or other compounds...

ATM4 und ATM4-glucuronide

Discrimination between street heroin consumption and poppy seed ingestion represents a major toxicological challenge in daily routine work. Now it is known the presence of acetylated thebaine metabolites ATM4 und ATM4 glucuronide (ATM4G) only originating from thebaine during heroin synthesis followed by metabolic reactions after administration. Therefore these substances allow as marker a clear differentiation between illegal heroin users and exposure to poppy seeds. ASCA GmbH has successfully...

Doxycycline

Doxycycline is a member of the tetracycline antibiotics. Tetracyclines are partly natural types of Streptomyces and partially semi-synthetic antibiotics with an extraordinarily broad spectrum of activity. They were the first major group of antibiotics for which the term “broad-spectrum” were used. The substances chlortetracycline, oxytetracycline, tetracycline and doxycycline are approved for the treatment of animals intended for foodstuff production. Their use requires that waiting periods be...

Digitoxigenin-monodigitoxoside & Digitoxigenin-bisdigitoxoside

Digitoxigenin-monodigitoxoside and Digitoxigenin-bisdigitoxoside are metabolites of digitoxin. The cardiac glycoside digitoxin, which possesses both potent cardiac  and anticancer activities, is the combination of two natural products, the aglycon digitoxigenin and the trisaccharide digitoxose. Recently, was constructed a neoglycoside library of digitoxin analogues with improved anticancer activity yet lower cardiotoxicity. To delineate the pharmalogical role the tris-2-deoxy sugar plays in...

New packaging unit for alternaria toxins

Alternaria toxins are characterized by a very wide range. The literature already describes more than 70 different mycotoxins. The best-known of these are alternariol (AOH), alternariol monomethyl ether (AME), tenuazonic acid (TEA), tentoxin (TEN) and altenuene (ALT). Now we can offer you the following native and stable isotopically labeled Alternaria toxins in addition to our standard packaging units (1 - 2000 mg) also in the amount of 100 μg: [gview...

beta- and gamma-Lumicolchicine

Colchicine is a toxic natural product and secondary metabolite, originally extracted from plants of the genus Colchicum (Colchicum autumnale, also known as autumn crocus, meadow saffron or naked ladies). Colchicine is a medication most commonly used to treat gout. In addition to gout, it is used to treat familial Mediterranean fever, pericarditis, and Behçet's disease. The use of colchicine as a drug in food-producing animals is prohibited in the European Union. Alpha, beta, and...
