Mwachidule	3, 4-dihydroxy-2 '-chloroacetophenone ndiye chinsinsi chapakatikati pakuphatikizika kwa carbamot. Carbazil imadziwikanso kuti magazi, adrenal pigment ammonia urea sodium salicylate, yomwe imagwiritsidwa ntchito makamaka pakuwonjezeka kwa capillary permeability chifukwa cha magazi.
Gwiritsani ntchito	Wapakatikati wa hemostatic mankhwala anluoxue, adrenomimetic mankhwala gashaler, etc.
njira yopanga	onjezani catechol ndi chloroacetic acid mumphika wouma, kwezani kutentha mpaka 60 °c, ndikuyambitsa, 85-90 ° C kutchinjiriza 0.5h. Kuzizira mpaka pansi pa 65 ℃, onjezerani phosphorous oxychloride, itani pa 60-70 ℃ kwa 4h,70-80 ℃ kwa 4h. Pamene kuli kovuta kusonkhezera reactants wandiweyani, kuwonjezera madzi, kwezani kutentha, ndi hydrolyze pa 90-100 ℃ kwa 0,5h. Makhiristo adakhazikika mpaka pansi pa 10 ° C., ndikusefedwa. Nkhani yolimba idatsukidwa ndi madzi mpaka osalowerera kuti mupeze 2-chloro-3 ',4'-dihydroxyacetophenone.
