CRYSTALLINE FORM OF 4-[5-[3-CHLORO-5-(TRIFLUOROMETHYL)PHENYL]-4,5-DIHYDRO-5-(TRIFLUOROMETHYL)-3-ISOXAZOLYL]-N-[2-OXO-2-[(2,2,2-TRIFLUOROETHYL)AMINO]ETHYL]-1-NAPHTHALENECARBOXAMIDE Russian patent published in 2016 - IPC C07D261/04 A01N43/80 A01P7/02 A01P7/04 A01N25/12 

FIELD: chemistry.

SUBSTANCE: invention relates to crystalline polymorph of 4-[5-[3-chloro-5-(trifluoromethyl)phenyl]-4,5-dihydro-5-(trifluoromethyl)-3-isoxazolyl]-N-[2-oxo-2-[(2,2,2-trifluoroethyl)amino]ethyl]-1-naphthalenecarboxamide hydrate, representing form B, characterised by presence in powder X-ray diffraction pattern of at least reflexes at the following angle 2θ values: 17.433, 18.586, 20.207, 20.791, 21.41, 22.112, 23.182, 24.567, 27.844. Invention relates to composition for protection of animal from invertebrate pest-parasite, containing parasiticidally effective amount of polymorph form B. Invention also relates to method for control of invertebrate pest-parasite, which includes interaction of invertebrate pest-parasite or its habitat with biologically effective amount of polymorph form B. Habitat represents plant or animal.

EFFECT: obtaining thermally stable crystalline polymorph of 4-[5-[3-chloro-5-(trifluoromethyl)phenyl]-4,5-dihydro-5-(trifluoromethyl)-3-isoxazolyl]-N-[2-oxo-2-[(2,2,2-trifluoroethyl)amino]ethyl]-1-naphthalenecarboxamide hydrate.
