ʻŌmaʻomaʻo Bromocresol me CAS 76-60-8
He mea hoʻoheheʻe iki ka ʻōmaʻomaʻo Bromocresol i ka wai a hoʻoheheʻe ʻia i ka ethanol, ether, ethyl acetate, a me benzene. He mea maʻalahi loa i ka alkali, huli ka ʻōmaʻomaʻo Bromocresol i kahi kala polū-ʻōmaʻomaʻo kūikawā i ka wā e hālāwai ai me nā hopena wai alkaline. Hiki ke hoʻohana ʻia ka ʻōmaʻomaʻo Bromocresol ma ke ʻano he hōʻailona, e ʻike ʻia ana he melemele ma ka pH 3.8 a me ka polū-ʻōmaʻomaʻo ma ka pH 5.4.
| Nā Mea | Nā kikoʻī |
| PH (wā hoʻololi) | 3.8 (melemele ʻōmaʻomaʻo) -5.4 (polū) |
| Ka lōʻihi o ka nalu omo (nm) λ1（PH 3.8） λ2（PH 5.4） | 440~445 615~618 |
| Ka helu omo nuipa, L/cm · g α1（λ1PH 3.8, hāpana maloʻo） α2（λ2PH 5.4, hāpana maloʻo) | 24~28 53~58 |
| Hoʻāʻo hoʻoheheʻe ʻana o ka ethanol | hoʻoholo |
| Koena puhi (helu ʻia he sulfate) | ≤0.25 |
| Pohō ma ka maloʻo ʻana | ≤3.0 |
1. ʻO ka ʻōmaʻomaʻo ʻo Bromocresol ka mea hoʻoheheʻe cell
2. ʻO ka ʻōmaʻomaʻo Bromocresol he hōʻailona Acid-base, ka loli kala pH mai 3.8 (melemele) a i 5.4 (uliuli-ʻōmaʻomaʻo)
3. Hoʻohana pinepine ʻia ka paʻakai sodium ʻōmaʻomaʻo Bromocresol i ka hoʻoholo ʻana o ke kala o ka acidity a me ka alkalinity. Hoʻohana ʻia ka hopena paʻakai sodium a Bromocresol green ma ke ʻano he mea hana kala no ke ana ʻana i ka waiwai pH e ka spectrophotometry. Hoʻohana ʻia ma ke ʻano he reagent no ka chromatography papa lahilahi e hoʻoholo ai i nā hydroxycids aliphatic a me nā alkaloids, a ma ke ʻano he mea hoʻokaʻawale a me ka hoʻokaʻawale no ka hoʻoholo photometric o nā cations ammonium quaternary.
