[628‐13‐7] C5H6ClN (MW 115.57) InChI = 1S/C5H5N.ClH/c1‐2‐4‐6‐5‐3‐1;/h1‐5H;1H InChIKey = AOJFQRQNPXYVLM‐UHFFFAOYSA‐N (cleavage of oxiranes to chlorohydrins; cleavage of phenol methyl ethers; removal of N‐trityl protecting groups; catalyst for Fischer indole synthesis) Alternate Name: pyridine hydrochloride. Physical Data: mp 144 °C (dec). Solubility: sol water, chloroform, ethanol; insol ethyl ether. Form Supplied in: white hygroscopic crystalline solid. Preparative Methods: precipitates as a 98% yield of 99.8% pure white crystals when Hydrogen Chloride gas is passed through a solution of Pyridine in ether. Purification: recrystallize from chloroform/ethyl acetate and wash with ethyl ether. Can be dried by refluxing in benzene with azeotropic removal of water. Handling, Storage, and Precautions: stable solid, with no apparent decomposition after several years of storage at room temperature. The salt is very hygroscopic and must be protected from moist air.
