In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 870-72-4, name is Hydroxymethanesulfonic Acid Sodium Salt, the common compound, a new synthetic route is introduced below. 870-72-4
3, 9-Bis (sodium methylenesulfonato)-3, 6, 9, 15-tetraazabicyclo [9. 3. IJpentadeca- 1(15),11,13-triene (10). 3,6, 9, 15-tetraazabicyclo- [9. 3. 1] pentadeca-1 (15), 11, 13-triene (PYCLEN) (8) (2 g, 9.7 mmol) was dissolved in 20 ml water and the pH was adjusted to 5 using 6N HCl. The sodium formaldehyde bisulfite (9) (2.65g, 19.77 mmol) was then added in one portion and the pH was maintained at 7.0 using IN KOH. When no further drop in pH was detected, the pH was raised to 8.5 followed by freeze-drying to give the product as a white solid(quantitative). 1H NMR (D2O)8 2.87 (t, -CH2-, 5,7-cyclic, J H-H = 5.2 Hz, 4 H), 3.18 (t, -CH2-, 4, 8-cyclic, JH-H= 5. 2 Hz, 4 H), 3.85 (s, -CH2-, 2,10- cyclic, 4 H), 4.11 (s, N-CH2-S, 4 H), 7.03 (d, 3,5-py, JH-H = 7.7 Hz, 2 H), 7.55 (t, 4-py, J H-H = 7.7 Hz, 1 H); 13 C {1H} NMR(D20) 6 48.52 (-CH2-, 5,7-cyclic), 54.04 (-CH2-, 4,8- cyclic), 58.92 (-CH2-, 2,10-cyclic), 75.09 (N-CH2-S), 123.90 (3,5-py), 141.37 (4-py), 161.89 (2,6-py).
Statistics shows that 870-72-4 is playing an increasingly important role. we look forward to future research findings about Hydroxymethanesulfonic Acid Sodium Salt.
