We are pleased to introduce the newly synthesized deuterated Prosulfuron and two of its metabolites. Prosulfuron is highly soluble, volatile, has a high potential for leaching into groundwater, and can be very persistent in aquatic systems. Prosulfuron and its two metabolites are ecotoxic and show adverse effects on living organisms including mammals. A recent regulation […]

Octamethylcyclotetrasiloxane-d12 (D4)

We are pleased to introduce the recently synthesized deuterated Octamethylcyclotetrasiloxane (D4), one of the most abundant siloxanes in the environment. This substance is used by consumers in cosmetics and personal care products, washing and cleaning products, polishes and waxes. It is also used in scientific research and development, and its industrial use includes textile treatment […]

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 […]

Sulfonylurea Herbicides

We are pleased to introduce the following compounds, recently synthesized for your analytical needs. 2-Amino-4-methoxy-6-methyl-1,3,5-triazine is a metabolite of 10 different pesticides; iodosulfuron-methyl-sodium, iodosulfuron, triasulfuron, tribenuron-methyl, prosulfuron, chlorsulfuron, thifensulfuron, thifensulfuron-methyl, metsulfuron-methyl, and metsulfuron, according to the Pesticide Properties DataBase (PPDB), two of which are also part of our portfolio. Chlorsulfuron and Thifensulfuron-methyl-(methoxycarbonyl) are herbicides used […]

UV absorbers

We are introducing our newly synthetized and labeled UV absorbers, which are widely used as sunscreen agents and in many cosmetic products. 2-Ethylhexyl 4-methoxycinnamate  and Ethyl trans-4-methoxycinnamate-d3 were selected for inclusion in the 3rd watch list as substances to be monitored under the water framework directive, as described in the Joint Research Centre‘s (European Commission’s […]
