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.
