The IUPAC name of Sulfanilic acid is 4-aminobenzenesulfonic acid. With the CAS registry number 121-57-3, it is also named as Aniline-4-sulfonic acid; Benzenesulfonic acid, 4-amino-. The product's categories are intermediates of dyes and pigments, inorganic & organic chemicals and organics. It is greyish-white crystals or powder which is stable and incompatible with strong oxidizing agents. It will produce toxic nitrogen oxide and sulfur oxide gases when buring. So the storage environment should be ventilate, low-temperature and dry. Keep Sulfanilic acid separate from raw materials of food.

The other characteristics of Sulfanilic acid can be summarized as: 
(1)ACD/LogP:  -1.568; (2)# of Rule of 5 Violations:  0; (3)ACD/LogD (pH 5.5):  -5.05; (4)ACD/LogD (pH 7.4):  -5.07; (5)ACD/BCF (pH 5.5):  1.00; (6)ACD/BCF (pH 7.4):  1.00; (7)ACD/KOC (pH 5.5):  1.00; (8)ACD/KOC (pH 7.4):  1.00; (9)#H bond acceptors:  4; (10)#H bond donors:  3; (11)#Freely Rotating Bonds:  2; (12)Index of Refraction:  1.63; (13)Molar Refractivity:  40.72 cm3; (14)Molar Volume:  114.49 cm3; (15)Surface Tension:  67.5469970703125 dyne/cm; (16)Density:  1.513 g/cm3.
