Aspectus-White vel Fere Alba Crystallina pulveris
Damnum in siccitate in 105 pro 4 horis: non plus quam 1.50% sui ponderis amittit.
Residere in Ignitione non plus quam 0,1%.
Metalla gravia-non plus quam 0.02%.
Fluoride-Misce 70 mL solutione potassii chloridi recenter praeparati cum solutione chloridi isopropyl 30 mL, electrodam liquido supernatante imple, et permittit electronicum manere in mixtione non minus quam 2 horis ante utendum, vel potius pernoctare.
Cum mensuris capiendis, solutionem 150-mL compensatoris transferas, et electrodes immergas.Insert polytefico-libratum in compensatorem moventem, poculum in movente magnetico cacumine insulato habentem, movere permitte, donec aequilibrium attingatur (circiter 1 ad 2 minuta).Electrodes inter mensuras eluam et exsiccant, cavens ne crystallum in electrode specifico scalpturo.
Metire potentialem uniuscuiusque Parasceves Latin, et retrahitur fluoride machinatur, in mg per 100 mL, versus potentialem, in mV, in charta semilogarithmica.Metire potentialem Praeparationis Test, et ex norma curva determinant intentionem fluoride, in mg per 100 mL.Recipis fluoride in portione Flucytosini sumpta formula:
C / 10
in qua C est concentratio fluoride, in mg per 100 mL, a curva mensura: non plus quam 0.05% fluoride inuenitur.
Fluorouracil-Dissolve 250 mg in 10 mL mixtionis acidi glacialis et aquae (4:1).Applica 20 µL huius solutionis ad laminam chromatographicam tenui-straminis obductis cum strato chromatographico silicae gel mixtionis 0,5-mm.Ad eandem laminam applicamus 20 µL, in 10-µL incrementis 0.025 mg per mL solutionem USP Fluorouracil RS in mixtione acidi acetici et aquae glacialis (4, 1).Chromatogrammum evolvere in mixto acido chloroformi et glaciali acetico (13:7) donec frontem solvens non minus quam 14 cm ab origine movit.Remove bracteam e conclavi elaborando, et solvendo evaporare permitte.Maculas in lamella collocare observando sub radiis brevibus necem UV: macula quaelibet e solutione sub experimento non maior est magnitudine et intensione quam macula in respectivo RF per solutionem Latinam productam, respondens non plus quam 0.1% of. fluorouracil.
Assay-Plac circa 400 mg Flucytosini accurate perpensa, in 250 mL compensatur, adde 150 mL mixturam 2 voluminum acidi glacialis acetici et 1 voluminis anhydridis acetici, et solve, si opus est, leniter calefaciens.Titrate potentiometrice cum acido perchlorico 0.1 N VS, systemate electrode vitri calomel utens.Fac blank determinationes, et emendas quamlibet necessarias.Quodlibet mL ex 0.1 N acidi perchlorici aequipollet 12.91 mg C4H4FN3O.Flucytosina non minus quam 98.5 centesimas continet et non plus quam 101.0 centesimas C4H4FN3O, fundamento siccato computata.
