Dub 3 CAS 4197-25-5 Taw qhia

Sudan Dub B yog cov organic dye nrog cov tshuaj npe methylene xiav. Nws yog ib qho tsaus xiav crystalline hmoov nrog zoo solubility hauv dej.
Nws kuj tau siv dav hauv histology ua cov tshuaj pleev xim rau hauv lub tshuab tsom iav kom stain hlwb thiab cov ntaub so ntswg kom pom yooj yim.

Cov txheej txheem rau kev npaj ntawm Sudan dub B yog feem ntau tau los ntawm cov tshuaj tiv thaiv ntawm Sudan III thiab methylene xiav. Sudan Dub B kuj tuaj yeem tau txais los ntawm kev txo qis los ntawm methylene xiav.

Cov ntaub ntawv kev nyab xeeb hauv qab no yuav tsum tau saib xyuas thaum siv Sudan Black B: Nws ua rau khaus ntawm qhov muag thiab tawv nqaij, thiab kev sib cuag ncaj qha yuav tsum zam thaum kov. Kev tiv thaiv tsim nyog, xws li cov hnab looj tes kuaj thiab tsom iav, yuav tsum hnav thaum tuav lossis kov. Tsis txhob nqus cov hmoov los yog tov ntawm Sudan Black B thiab tsis txhob noj los yog nqos. Cov txheej txheem kev khiav hauj lwm kom raug yuav tsum tau ua raws li hauv chav kuaj thiab yuav tsum tau siv nyob rau hauv qhov chaw zoo.
