WebStep 2: Adjust pH to 7.2 with concentrated HCl. The solution will have a pH between 10.0 – 11.5. Add concentrated HCl (≈ 45 ml) to adjust pH to 7.2. Tip: You can set the desired pH (between 6.8 – 9) of the solution at this point with the addition of HCl. Precautions: 1. Don’t adjust the pH when the solution is hot. Web4-Dimethylaminopyridine (DMAP) is a derivative of pyridine with the chemical formula (CH 3) 2 NC 5 H 4 N. This white solid is of interest because it is more basic than pyridine, owing to the resonance stabilisation from the NMe 2 substituent.. Because of its basicity, DMAP is a useful nucleophilic catalyst for a variety of reactions such as esterifications with …
