What is CINNOLINE?
Definition
ChEBI: An azaarene that is the 1,2-diaza analogue of naphthalene. The parent of the class of cinnolines.
Purification Methods
It is distilled at high vacuum, then recrystallised from pet ether. Keep it under N2 in sealed tubes in the dark at 0o. The hydrochloride [5949-24-6] M 166.6 crystallises from EtOH/Et2O and has m 156-158o (yellow monohydrate), and dehydrates on sublimation at 110-115o/3mm. The picrate has m 196-196.5o.
