Chii chinonzi Bromocresol Green NeCAS 76-60-8?

Bromocresol yegirini inonyungudika zvishoma mumvura uye inonyungudika mu ethanol, ether, ethyl acetate, uye benzene. Inonyatsonzwa kune alkali, Bromocresol yegirini inoshandura yakasarudzika yebhuruu-ruvara rwegirinhi paunosangana nealkaline aqueous mhinduro. Bromocresol yegirini inogona kushandiswa sechiratidzo, ichiita yero papH 3.8 uye yebhuruu-girinhi papH 5.4.

Application

1.Bromocresol green is Cell staining agent
2.Bromocresol green is Acid-base indicator, pH color change range 3.8 (yellow) kusvika 5.4 (blue-green)
3.Bromocresol green sodium munyu inowanzoshandiswa mu colorimetric determination ye acidity uye alkalinity. Bromocresol green's sodium munyu mhinduro inoshandiswa se colorimetric agent yekuyera pH kukosha ne spectrophotometry. Inoshandiswa se reagent kune yakaonda layer chromatography kuona aliphatic hydroxyacids uye alkaloids, uye seanobvisa uye kupatsanura mumiriri weiyo photometric kutsunga kwequaternary ammonium cations.
