2-Acetyl-isonicotinic acid methyl ester; CAS 138715-82-9

2-Acetyl-isonicotinic acid methyl ester (CAS 138715-82-9, molecular formula C9H9NO3, molecular weight 179.17) is supplied by Zhengzhou Yuanli Biological Technology Co., Ltd for research use only, rather than manufactured directly. It appears as a white to off-white crystalline solid at 98% purity by HPLC; the source listing's synonym referencing a terpyridine tricarboxylic ester appears inconsistent with this molecular weight and should be treated with caution. No samples are currently offered, though the product is listed across North America, Europe, Asia, the Middle East, and Africa.
