설파닐산 C화학적 특성, 용도, 생산
개요
Sulfanilic acid (4-amino benzene sulfonic acid ) is an off-white crystalline solid which finds application in quantitative analysis of nitrate and nitrite ions. The solid acid exists as a zwitterion, and has an unusually high melting point.
화학적 성질
greyish-white crystals or powder용도
Sulfanilic Acid (Sulfadimethoxine EP Impurity D) is a toxic metabolite of Tartrazine (T007700). Used as Ehrlich’s reagent, for detecting of nitrites. Antibacterial.주요 응용
As the compound readily form diazo compounds, it is used to make dyes and sulpha drugs . This property is also used for the quantitative analysis of nitrate and nitrite ions by diazonium coupling reaction with N-(1-Naphthyl) ethylene diamine , resulting in an azo dye, and the concentration of nitrate or nitrite ions were deduced from the color intensity of the resulting red solution by colorimetry.It is also used as a standard in combustion analysis.
정의
ChEBI: An aminobenzenesulfonic acid that is aniline sulfonated at the para-position.일반 설명
White powder with faint purple tinge. Grayish-white flat crystals. Becomes anhydrous at around 212°F. Low toxicity (used medicinally).공기와 물의 반응
Insoluble in water.반응 프로필
Sulfanilic acid is an amino acid. Reacts weakly with both acids and bases.화재위험
Flash point data for Sulfanilic acid are not available, however Sulfanilic acid is probably combustible.Purification Methods
Crystallise the acid (as dihydrate) from boiling water. Dry it at 105o for 2-3hours, then over 90% H2SO4 in a vacuum desiccator. The S-benzylisothiuronium salt has m 187o (from aqueous EtOH). [Beilstein 14 IV 2655.]설파닐산 준비 용품 및 원자재
