What is Sulphanilic acid formula?
C6H7NO3SSulfanilic acid / Formula
Is sulfanilic acid toxic?
Ingestion: May cause gastrointestinal irritation with nausea, vomiting and diarrhea. Inhalation: May cause respiratory tract irritation. Chronic: Effects may be delayed. Repeated or prolonged exposure may cause allergic reactions in sensitive individuals.
What is sulfanilic acid used for?
They are derivatives of sulfanilic acid (p-aminobenzenesulfonic acid), and they are used for prophylactic and therapeutic treatment of infections caused by gram-positive and gram-negative bacteria and some protozoa (causative agents of malaria, toxoplasmosis, etc.).
How do you dissolve sulfanilic acid?
For the control, dissolve 0.20 g in about 75 mL of water, add 0.00025 mg of nitrite ion (NO2), and dilute with water to 100 mL. To each solution, add 5 mL of sulfanilic-1-naphthylamine solution (described below), and allow to stand for 10 min.

How do you make sulphanilic acid?
The basic principles of chemistry that Sulphanilic Acid is produced are completed by following two processes: (1) is by aniline and sulfuric acid generation salt-forming reaction; (2) anilinesulfonic acid salt is through dehydration, the obtained Sulphanilic Acid of molecular transposition (transposition).
How do you make sulfanilic acid?
Is sulfanilic acid flammable?
ICSC 0569 – SULFANILIC ACID. Combustible. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames.
In what test was the sulphanilic acid used?
Pauly’s test is based on the principle of coupling between the amino acids and the diazonium ion formed in the reagent. The pauly’s reagent consists of sulphanilic acid dissolved in concentrated hydrochloric acid. The sulfanilic acid undergoes diazotization in the presence of sodium nitrate and hydrochloric acid.
Is sulphanilic acid soluble in water?
sulphanilic acid is soluble in water.
Is SO3H an activator?
Common activating groups (not a complete list): Alkyl, NH2, NR2, OH, OCH3, SR. Common deactivating groups (not a complete list): NO2, CF3, CN, halogens, COOH, SO3H.
Is SO3H a good leaving group?
Sulfonic acids are very strong acids (pKa ~ -7). The most common sulfonic acid is p-toluenesulfonic acid. The conjugate bases of sulfonic acids are called sulfonate anions and are resonance stabilized. Consequently, sulfonate anions make good leaving groups.

How do you make Sulphanilic acid?
Why is Nitro a deactivator?
The nitro group strongly deactivates the benzene ring towards electrophilic substitution. Nitro group is electron withdrawing group and thus causes electron deficiency at ortho and para positrons as is clear from the resonating structures of nitro benzene.
Why Is fluoride a bad leaving group?
Exception: Fluorine is a poor leaving group. F⁻ is a small ion. Its high charge density makes it relatively unpolarizable. The leaving group needs to be polarizable to lower the energy of the transition state.
Is CF3 a meta director?
So the meta product is formed preferentially. This is why CF3 is a “meta director” (although I prefer to call groups like CF3 “ortho-para avoiders”. This also applies to other meta directors such as NO2, CN, SO3H, ketones, and so on.
Why is nitro a meta director?
If the opposite is observed, the substituent is called a meta directing group. Thus, the methyl group is an ortho, para directing group. Thus, the nitro group is a meta directing group. Ortho, para directing groups are electron-donating groups; meta directing groups are electron-withdrawing groups.
What is a deactivator in chemistry?
Deactivator (deactivating group): In electrophilic aromatic substitution, an aromatic ring substituent that decreases nucleophilicity and arenium ion stability (relative to a hydrogen atom), thereby causing the reaction to be slower than the same reaction on benzene itself.
