Reference of 5832-43-9, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 5832-43-9, name is 4-Methyl-5-nitropicolinic acid. This compound has unique chemical properties. The synthetic route is as follows.
Methyl 4-methyl -5-nitropicol i nateTo a solution of 4-methyl-5-nitropicolinic acid (5.0 g, 27.5 mmol) in methanol (60 mL) was slowly added concentrated sulfuric acid (4.39 mL, 82 mmol) and the mixture was refluxed under argon for 18 h. The volatiles were evaporated and a sat. aq. solution of NaHCO3 was added slowly until the aqueous phase showed a pH of 7-8. The resultant mixture was extracted with CH2CI2 (x3), the combined organic extracts were dried (phase separator) and concentrated under vacuum. MS (UPLC-MS): 197.0 [M+H]+, tR (HPLC conditions h): 1.99 mm.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 5832-43-9, 4-Methyl-5-nitropicolinic acid.
