What’s th application of benzocaine?

1. Properties of Aromatic First Amines

1) Weakly alkaline

2) Easy to oxidative deterioration

Application: It is necessary to take anti-oxidation measures when preparing its liquid, such as adjusting the pH to 3.5 to 5.5, and strictly control the sterilization temperature and time, and it is appropriate to sterilize it by circulating steam at 100 °C for 30 minutes.

3) Diazo coupling reaction

Application: Identification. In dilute hydrochloric acid, it forms a diazonium salt with sodium nitrite, and a coupling reaction occurs with basic β-naphthol to form a red azo compound.

4) Condensation reaction with p-aromatic aldehyde

Application: Identification. Under the condition of hydrochloric acid, it can condense with p-dimethylaminobenzaldehyde to generate yellow Schiff base.

5) Application: Examination of procaine hydrochloride p-aminobenzoic acid impurities by thin-layer method.

2. The nature of the ester bond

Easy hydrolysis failure.

Application: It is necessary to take anti-oxidation measures when preparing its liquid, such as adjusting the pH to 3.5 to 5.5, and strictly control the sterilization temperature and time, and it is appropriate to sterilize it by circulating steam at 100 °C for 30 minutes.

Application: should be shaded, sealed and stored.

Application: Identification. Its aqueous solution is added with sodium hydroxide solution, then a white precipitate of procaine is precipitated, and the ester is hydrolyzed by heating to produce diethylaminoethanol (steam turns red litmus paper blue) and sodium p-aminobenzoate, let it cool, add hydrochloric acid to acidify, namely A white precipitate of p-aminobenzoic acid is precipitated, which can be dissolved in an appropriate amount of hydrochloric acid.
