The subject-matter of the invention is the B form of ethyl [(7S)-7-[(2R)-2-(3-chlorophenyl)-2-hydroxyethylamino]-5,6,7,8-tetrahydronaphth-2-yloxy]acetate hydrochloride, of use as a medicament, which exhibits in particular the following physical characteristics:
characteristic IR absorption peaks (cm
−1
): 2780, 2736, 1722, 1211;
melting point: 129+/−2° C.;
characteristic lines of the powder X-ray diffraction diagram (to within 0.1(2&thgr;)): 7.69, 9.83, 13.95, 16.58, 18.70, 20.40, 21.57, 23.40, 24.15 and 25.64.
The product can be obtained by salification of the base or recrystallization of the salt from an alcohol.
