[Chemical Properties] WHITE POWDER
[Uses] Potassium tetraborate tetrahydrate (K₂B₄O₇.4H₂O) may be employed in the preparation of puffed and dense forms of anhydrous potassium tetraborate (purity = 99.5%, bulk density = 0.4 and 0.7gcm^-3). It may be used for the preparation of saturated K₂B₄O₇ solution required for the quantification of polyamines in various biological samples by HPLC.
[General Description] Potassium tetraborate tetrahydrate is a hydrated tetraborate salt of potassium. Its crystal structure has been examined. Its crystals belong to the orthorhombic crystal system with space group P2₁2₁2₁. Aqueous solution of potassium tetraborate tetrahydrate on evaporation affords single crystals.
