  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 415 nm. The detection range of boron in sample solutions is 1-6礸/ml. To detect boron in plant samples, EDTA is used to mask cupper, iron, and aluminum ions. Azomethine H is used to detect microgram levels of boron in glass and steel samples.
