The lab supply company really wanted to make sure you knew what you were getting! That bottle label stating "Succinic acid (contains succinic acid)" is the chemical equivalent of "water contains water" or "this floor is made of floor." The redundancy is peak lab supply humor - they're just making absolutely, positively, 100% certain you understand that your succinic acid does, in fact, contain... succinic acid. Chemistry suppliers taking product labeling to hilariously unnecessary levels of specificity. Next they'll be telling us that H₂O is wet!
