5-Sulfosalicylic Acid Dihydrate

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.

5-Sulfosalicylic Acid is used as Blood Fixative in Forensics. It is highly recommended for setting bloody prints or footwear impressions before performing enhancement techniques that utilize an aqueous based formulation. This will prevent loss of detail of the impression that could be caused during enhancement.
