性质描述: 白色针状结晶。熔点134-136℃，易溶于冰乙酸，几乎不溶于乙醚、氯仿和二硫化碳。
生产方法: 将50g2-甲基吡啶加入2500ml水中，加热搅拌，加入90g高锰酸钾，约1h后再加入第二份90g高锰酸钾。补加500ml水并继续加热2-2.5h，直至紫色消失。冷却，滤出二氧化锰沉淀，用热水洗涤。将滤液减压浓缩，过滤。浓缩液用浓盐酸酸化至刚果红酸性后蒸发至干，将其与250ml95%乙醇检煮回流1h。过滤，滤饼用95%乙醇提取，合并乙醇滤液及提取液，通入干燥的氯化氢，至晶体开始析出为止。冷却至10℃，再通氯化氢至馏和，滤出吡啶甲酸盐酸盐，干燥后得43-44g（盐酸盐熔点210-212℃）。
用途: 有机合成中间体。
