Characterisation level

* Mass balance is performed on every molecule. The only exceptions are cases where the chemistry of the molecule prevents it, for example oils and highly volatile substances, on which some of the required measurements cannot be made: in those cases the CoA states how the content was assigned.

An organophosphate insecticide that blocks the enzyme acetylcholinesterase in insects, first registered in the United States in 1956: it is used in agriculture, in mosquito and fruit fly control programmes and, at low concentrations, in lotions against head lice.

Did you know?Mammals and birds have more carboxylesterase than insects: they break malathion down before it can turn into malaoxon, its active form, which explains its low toxicity to them.

Frequently asked questions

Is mass balance always performed?

Yes, on every molecule. The only exceptions are cases where the chemistry of the molecule prevents it: for example oils and highly volatile substances, on which some measurements (such as thermogravimetry) cannot be made. In those cases the CoA states which method was used to assign the content.

Can I ask for a different quantity?

Yes. The quantities are only suggestions: choose "Other" and enter the milligrams or grams you need.

Which level should I choose?

Level 1 is enough for most routine testing. Level 2 adds an independent qNMR content value and is meant for labs that need to qualify an in-house primary standard. For peptides and similar molecules, Level 2 is not available.

When will I get the quote?

Within 24 working hours, with price, availability and delivery time.
