Bromocresol Purple CAS 115-40-2
ʻAʻole hiki ke hoʻoheheʻe ʻia ka Bromocresol Purple i ka wai, hoʻoheheʻe ʻia i ka ethanol a ʻike ʻia he melemele, hoʻoheheʻe ʻia i loko o ka sodium hydroxide dilute a me nā hopena sodium carbonate dilute a ʻike ʻia he poni ʻulaʻula, me kahi kiko heheʻe o 241-242 ℃. ʻO ka hoʻohana nui ʻana o ka bromocresol poni ma ke ʻano he hōʻailona acid-base a me kahi hōʻailona titration non-aqueous.

ʻO ka hōʻailona kumu waikawa poni Bromocresol, i hoʻohana ʻia no ka nānā ʻana i ka chromatographic a me ka titration non-aqueous. Ka laulā loli kala PH: 5.2 (melemele) -6.8 (poni). Hōʻailona adsorption. Kūlana kūloko no ka chromatography waikawa amino. Titration paʻakai kālā o ka thiocyanate. Ka hoʻoheheʻe ʻana o nā protein serum me ka hoʻohana ʻana i ka spectrophotometry.
Hoʻopili pinepine ʻia i loko o 25kg / pahu, a hiki ke hana ʻia kahi pūʻolo i hoʻopilikino ʻia.
