Propranolol hydrochloride | C16H22ClNO2 - PubChem

Propranolol Hydrochloride is the hydrochloride form of propranolol, a synthetic beta-adrenergic receptor blocker with antianginal, antiarrhythmic, and antihypertensive properties. Propranolol competitively antagonizes beta-adrenergic receptors, thereby inhibiting beta-adrenergic reactions, such as vasodilation, and negative chronotropic and inotropic effects.

Mar 16, 2007 · Evaporate water from your aqueous reaction mixture by lyophilization – becaus eevaporating water on rotovap is fairly harsh unless you have a very good pump and rotovap. Adjust the pH of your mix prior lyophilzation to pH below 8.5 and you should be fine. Comment by milkshake — March 17, 2014 @ 12:19 pm

I would recommend buying a rotovap, Buchi brand as they are very useful for removing solvents from reaction mixtures. A fume hood is a must for most reactions, this should be your first priority if you plan on conducting work with organics. Many of the reagents that you will need or want can be synthesized from fairly common chemicals.
