Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C)
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

Novel process for synthesizing and a novel crystal form of agomelatin as well as pharmaceutical preparations containing these.[Reference: WebLink
METHODS AND RESULTS:
Producing agomelatin comprises reacting 7-methoxy-1-tetralone with cyanoacetic acid in presence of organo-ammonium carboxylate catalyst (V), contacting resulting 2-(7-methoxy-3,4-dihydro-1-naphthyl)acetonitrile (VI) with hydrogenation catalyst in presence of allylic compound to give 2-(7-methoxy-1-naphthyl)acetonitrile (VII), hydrogenating (VII) to give 2-(7-Methoxy-1-naphthyl)ethylamine hydrochloride (VIII) and acetylating. Producing agomelatin (N-(2-(7-methoxy-1-naphthyl)ethyl)acetamide) comprises: (i) reacting 7-methoxy-1-tetralone with cyanoacetic acid in the presence of an organoammonium carboxylate catalyst of formula (V) while removing water; (ii) contacting the resulting 2-(7-methoxy-3,4-dihydro-1-naphthyl)acetonitrile (VI) with a hydrogenation catalyst in the presence of an allylic compound to give 2-(7-methoxy-1-naphthyl)acetonitrile (VII); (iii) hydrogenating (VII) in the presence of Raney nickel in ethanol and treating the product with hydrochloric acid to give 2-(7-Methoxy-1-naphthyl)ethylamine hydrochloride (VIII); and (iv) reacting (VIII) successively with.
