5-Sulfosalicylic acid dihydrate is a sulfonated salicylic acid derivative.

Strong association with a range of metals makes 5-Sulfosalicylic acid useful as a metal scavenger.

It forms proton-transfer dye complexes with diazo compounds such as 4-(phenyldiazenyl)aniline. Proteins are precipitated upon complexation with 5-Sulfosalicylic acid, allowing qualitative analysis of the resultant turbidity formed in a sample by these complexes leaving solution.

Protein precipitation with 5-Sulfosalicylic acid has also been employed as a preparative measure for removing proteins prior to chromatographic analysis.

  • Precipitating and purifying proteins, peptides, and enzymes
  • Determining the concentration of certain substances in a solution, such as creatinine and uric acid
  • Preparing reagents and buffers for biochemical assays and diagnostic kits
  • Stabilizing and preserving biological samples and tissues for analysis
  • Assisting in the isolation and detection of certain drugs and metabolites in urine and blood samples
  • Removing unwanted substances, such as proteins and lipids, from biological samples before analysis.
