Application

Sodium phosphate monobasic dihydrate has been used for preparing phosphate buffer solution. It has also been used as a mobile phase for high-performance liquid chromatography.

Biochem/physiol Actions

Sodium phosphate monobasic also referred to as sodium dihydrogen phosphate is a chemical reagent possesses high buffering capacity and is used for preparing biological buffers. It was used as a phosphate supplement for determining whether phosphate supplementation can prevent rickets in very low birth weight infants with prenatal deficiency of phosphate.

A preliminary study showed that placental histology was abnormal for babies who subsequently had rickets. The findings--low plasma phosphate concentration; maximum percentage tubular reabsorption of phosphate; and high urinary calcium loss--are those of renal conservation of phosphate in the presence

A method has been developed to analyze residual tetracyclines (TCs) (oxytetracycline (OTC), tetracycline (TC), chlortetracycline (CTC), methacycline (MTC), doxycycline (DC)) in ovine milk, using high-performance liquid chromatography (HPLC) with a coulometric electrode array system. The samples were pretreated, using liquid-liquid
