Quinmerac Metabolites

  A complete assessment of residue values of all quinmerac metabolites has not been possible up until now due to the lack of availability of the two quinmerac metabolites BH 518-1 and BH 518-4. Today we are pleased to announce that we have added these two metabolites to our product portfolio. In the last review […]


6PPD-quinone (labelled and unlabelled)

We are introducing our newly synthesized native and labelled 6PPD-quinone, a highly toxic quinone transformation product of N-(1,3-dimethylbutyl)-N’-phenyl-p-phenylenediamine (6PPD), a worldwide commonly used tire rubber antioxidant. A recent study showed that this tire rubber-derived transformation product could occur at toxic concentrations in urban creeks with proximity to busy roadways in the pacific northwest of the […]


Alternaria toxin sulfate derivatives

Alternariol 3-Sulfate Ammonium Salt and Alternariol 9-Methyl Ether 3-Sulfate Ammonium Salt are the ammonium salts of a sulfate derivative of Alternariol and Alternariol 9-Methyl Ether, respectively, which are Alternaria mycotoxins and genotoxins, found in common edible crops. We have recently successfully synthesized these two mycotoxins for your analytical needs. More than 70 different mycotoxins have […]
