Azomethine H is a colorimetric reagent for boron detection.
It forms an orange complex with boron in aqueous solution. The molar absorptivity of this complex is 1.01x104 at 415nm. The detection range of boron in sample solutions is 1-6um per ml or 1.0-6ppm. To detect boron in plant samples EDTA is used to mask copper, iron and aluminium ions.
Boron determinations are used in,
1. Soil, plants, composts, manure, water and nutrient solutions
2. Glass and Steel samples (microgram levels of boron)
Azomethine H is also used in Electrocyclization Reactions in the synthesis of Martinellic acid, Spirotryprostatin A, Benzodiazepinones.
