- Description
- Probe for the colorimetric determination of boron in samples such us soils, plants, composts, manure, water, nutirent solution, glass or steel (microgram levels of boron). It forms an orange complex with boron in aqueous solution (absorption maxima at ~415nm). The detection range of boron in sample solutions is 1.0-6ppm. To detect boron in plant samples EDTA is used to mask copper, iron and aluminium ions. It is also used in electrocyclization reactions in the synthesis of martinellic acid, spirotryprostatin A and benzodiazepinones. Was shown to produce free radicals and might have anti-malarial and anti-cancer properties.
