Use
1. Determination of nitrite. Biochemical studies. Organic synthesis.
2. This product is an important intermediate of sulfonamides. This product for hemolytic streptococcus, meningitis, aureus antibacterial effect is strong, but because of poor effects, toxicity, rarely used for internal use, external use as "agent or ointment can control wound infection, but can cause an allergic reaction, so rarely used, now used as intermediates for synthesis of other sulfa drugs, foreign agricultural" yellow grass spirit "is also used as a synthetic materials.
3. Used as an analytical reagent, such as a spectrophotometric reagent for the determination of nitrite and sodium ferrocyanide nitrite. Used in biochemical research, organic synthesis and pharmaceutical industry.
4. The main raw materials for the synthesis of sulfonamides can be used for the preparation of crystalline sulfonamides for external use to reduce inflammation, and other sulfonamides, such as sulfamami
dine, sulfamethoxazine, and sulfamethyrimidine, etc. [1].
