[¦səl·fō¦sal·ə¦sil·ik ′as·əd]
(organic chemistry)
C7H6O6S A trifunctional aromatic compound whose dihydrate is in the form of white crystals or crystalline powder; soluble in water and alcohol; melting point is 120°C; used as an indicator for albumin in urine and as a reagent for the determination of ferric ion; it also has industrial uses.

The major objective of this study was to determine the reliability and accuracy of the sulfosalicylic acid test in the fast measurement of proteinuria.
Twenty patients had information concerning proteinuria; it was negative by urinalysis, sulfosalicylic acid, or 24-hour urine collection sample in 18 (90%) of them.
For confirmatory testing of other reagent strip constituents, commonly used tests include the sulfosalicylic acid test (SSA) for protein, and the Ictotest Tablet Test (Bayer) for bilirubin.
To precipitate proteins, the homogenates were treated with 5% sulfosalicylic acid (Sigma) in a 1:10 ratio of sulfosalicylic acid/homogenate (Lee and Slocum, 1988).
Urine specimens containing radiographic media will also show a delayed, false positive sulfosalicylic acid test for urine protein.
For proline evaluation 0.5g of plant leaf was ground with sulfosalicylic acid beside filtration.
Root samples (0.5 g) from each group were homogenized in 3% (w/v) sulfosalicylic acid and the homogenates were filtered through a filter paper.
Free amino acids were extracted with 10% sulfosalicylic acid solution.
The frozen aliquot was analyzed by ion-exchange amino acid chromatography using an Aminotac analyzer (Jeol) after deproteinization by 10-fold dilution in 200 g/L sulfosalicylic acid.
Plant material (1g), which consisted of young leaves, was ground with 10 ml of 3% sulfosalicylic acid. The homogenate was filtered and 2 ml of glacial acetic acid and 2 ml acid ninhydrin reagent were added to 2 ml of filtrate.
