Zheng, Hai-jin published the artcileSynthesis and property of a new type of chromogenic reagent of thiazolylazo, Name: Sodium 3-bromopropane-1-sulfonate, the publication is Huaxue Yanjiu (2004), 15(3), 42-44, database is CAplus.
The synthesis of 2-(4,5-dimethyl-2-thiazoleazo)-4-methyl-5-sulfopropylaminobenzoic acid is reported. Its chromogenic property with Cu2+, Ni2+, Co2+ was studied. It can form stable compounds with Cu2+, Ni2+, Co2+. The maximum absorptions of these compounds are at 628 nm, 590 run, 583 nm, and their molar absorptivities (ε) are 8.4 × 104, 5.8 × 104 and 4.8 × 104, resp. Also this material can be used as a good spectrophotometric chromogenic agent for some metal ions.
Huaxue Yanjiu published new progress about 55788-44-8. 55788-44-8 belongs to bromides-buliding-blocks, auxiliary class Bromide,Salt,Aliphatic hydrocarbon chain,Aliphatic hydrocarbon chain, name is Sodium 3-bromopropane-1-sulfonate, and the molecular formula is C15H14O3, Name: Sodium 3-bromopropane-1-sulfonate.
