Yintoni iBromocresol Purple CAS 115-40-2?

I-Bromocresol Purple ayinyibiliki emanzini, inyibilika kwi-ethanol kwaye ibonakala ityheli, inyibilika kwi-sodium hydroxide enyibilikisiweyo kunye ne-sodium carbonate enyibilikisiweyo kwaye ibonakala ibomvu ngombala omfusa, ineqondo lokunyibilika elingama-241-242 ℃. Ukusetyenziswa okuphambili kwe-bromocresol violet kukubonisa i-acid-base kunye ne-non-aqueous titration indicator.

Isicelo

Isalathisi se-Bromocresol Purple acid-base, esisetyenziselwa uhlalutyo lwe-chromatographic kunye ne-titration engeyiyo yamanzi. Uluhlu lokutshintsha kombala we-PH: 5.2 (tyheli) -6.8 (mfusa). Isalathisi sokufunxa. Umgangatho wangaphakathi we-amino acid chromatography. I-titration yetyuwa yesilivere ye-thiocyanate. Ukuna kweeproteni ze-serum kusetyenziswa i-spectrophotometry.
