6419-36-9, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 6419-36-9, name is 2-(Pyridin-3-yl)acetic acid hydrochloride. This compound has unique chemical properties. The synthetic route is as follows.
D56Pyridin-3-yI-acetic acid ethyl esterTo a solution of 3-pyridylacetic acid hydrochloride (40g, 230.41mmol) in ethanol (90 mL) was added sulfuric acid(73 g, 744.3 mmole, 98%) under N2. The reaction mixture was refluxed for 4 h, then cooled to rt. Ammonium hydroxide (250 mL, 25%) was added and extracted with DCM (500 mL) twice, dried over sodium sulfate, concentrated to afford the title product (33 g).
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 6419-36-9, 2-(Pyridin-3-yl)acetic acid hydrochloride.
