Chii chinonzi Bromocresol Green neCAS 76-60-8?

Bromocresol green inonyungudika zvishoma mumvura uye inonyungudika muethanol, ether, ethyl acetate, uye benzene. Inonyanya kunzwa alkali, Bromocresol green inoshanduka kuva neruvara rwebhuruu-girini kana ikasangana nealkaline aqueous solutions. Bromocresol green inogona kushandiswa sechiratidzo, ichioneka yeyero pa pH 3.8 uye bhuruu-girini pa pH 5.4.

Kushandiswa

1. Bromocresol green imhando ye "Cell staining agent"
2.Bromocresol green ndiyo inomiririra acid-base, pH color change range iri 3.8 (yero) kusvika 5.4 (bhuruu-girini)
3. Bromocresol green sodium salt inowanzo shandiswa pakuongorora acidity nealkalinity mu colorimetric. Bromocresol green's sodium salt solution inoshandiswa se colorimetric agent yekuyera pH value ne spectrophotometry. Inoshandiswa se reagent ye thin layer chromatography kuona aliphatic hydroxyacids ne alkaloids, uye se extraction and separation agent ye photometric determination ye quaternary ammonium cations.
