Product Highlights
Zearalenone and its major metabolites
Zearalenone (ZEN) - a mycotoxin produced by Fusarium species - is one of the most common food and feed contaminants. In addition to the "free" toxin a number of derivatives exist the partly be counted to the so-called "masked" mycotoxins. Zearalenone and its metabolites are structurally similar to estrogens, show high affinity for estrogen receptors and exert a negative impact on living organisms. We can provide the following standards for your investigations and analysis: [gview...
Metabolites of Dimethenamid-P
Dimethenamid-P is used as an herbicide in Europe, especially in maize and beet, but also in sunflower cultivation. The main metabolites and other known metabolites are found in soil, sediment and groundwater and are of importance with regard to consumer health protection. ASCA GmbH has successfully realized the synthesis of some metabolites of dimethenamid-P and can offer these as reference substances for residue analysis. (S)-Dimethenamid-P Metabolite M11 (S)-Dimethenamid-P Metabolite M27...
Masked mycotoxins
In recent years, there has been a lot of talk about so-called „masked mycotoxins“", also known as modified or matrix-associated mycotoxins and describes metabolites of mycotoxins. These metabolites of mycotoxins are formed in the plant, for example by conjugation. They often occur in Fusarium toxins and are considered as toxic as the original toxin. We can provide the following standards for your investigations and analysis on masked mycotoxins: [gview...
Metabolites of dimethachlor
Dimethachlor is used to control most annual grasses and broad-leaved weeds. The main metabolites and other known metabolites are found in soil, sediment and groundwater and are of importance with regard to consumer health protection. ASCA GmbH has successfully synthesized the key metabolites of dimethachlor and can offer these as native and labelled standards. [gview file="http://asca-berlin.de/files/wp-content/uploads/Dimethachlor-Metabolite.pdf"] We look forward to your...
Metabolites of alachlor
Alachlor is an herbicide from the chloroacetanilide family. It is the second most widely used herbicide for control of annual grasses and broadleaf weeds in crops, primarily on corn, sorghum and soybeans in the United States. Use of alachlor is illegal in the European Union. The active substance itself and its most important transformation products are detected as part of groundwater monitoring and are thus of importance in terms of drinking water quality. ASCA GmbH has successfully...
Prothioconazole
Prothioconazole is a fungicide of triazolinthiones for use both as a seed treatment and foliar spray to treat a variety of diseases in cereals. Prothioconazole and the transformation product Prothioconazole-S-methyl are detected in the water samples and are of importance with regard to consumer health protection. ASCA GmbH has successfully synthesized these substances and can offer these as native and labelled standards. Prothioconazol Prothioconazol-S-methyl Prothioconazol-S-methyl-d3 ...
Main metabolites of metazachlor
Metazachlor is used as a selective lead herbicide against weedy grasses in cabbage, tobacco, rapeseed and potato crops. The main metabolites of metazachlor are metazachlorosulphonic acid (BH 479-8) and metazachloric acid (BH 479-4). Both metabolites are found in groundwater and are of importance for the resulting raw water for drinking water production with regard to consumer health protection. ASCA GmbH has successfully synthesized these main metabolites of metazachlor and can offer these as...
Bisphenol A diglycidyl ether metabolites
Due to cytotoxicity and genotoxicity observed in in vitro studies, bisphenol A diglycidyl ether (BADGE) and its metabolites may pose a health risk to humans. Quantifying exposure is an essential step to assess health risks associated with this compound widely used in certain plastic products. ASCA GmbH can offer four BADGE metabolites with chemical purity >95%. [gview file="http://asca-berlin.de/files/wp-content/uploads/Bisphenol-Metaboliten.pdf"] We look forward to your...
Zearalenol standards
Mycotoxins are widespread contaminants of feed and food, meat, cheese, spices and beverages, coming from different kinds of fungi that grow on almost every kind of nourishment. Zearalenone and its major metabolites alpha- and beta-zearalenol are nonsteroidal estrogenic mycotoxins produced by Fusarium species. For your investigations and analysis, we can offer the following zearalenol standards: [gview file="http://asca-berlin.de/files/wp-content/uploads/Zearalenol.pdf"] Contact us for enquires...
Benalaxyl standards
Benalaxyl is a fungicide that has EU approval for use and is widely used. It has a low aqueous solubility, is quite volatile and a low potential for bioaccumulation. It is moderately persistent in soil systems and may be persistent in water systems. Residues of benalaxyl and its metabolites are analyzed in various fruits and vegetables, but also in water. For your investigations and analysis, we can offer the following benalaxyl metabolites: [gview...
