间苯二甲酸-5-磺酸钠，化学上称为5-SSIPA（Sodium 3,5-dicarboxybenzenesulfonate），是一种有机化合物，其化学式为C7H5NaO7S，分子量为266.16 g/mol。它是一种含有苯环的化合物，其中两个位置上的羧基（-COOH）被磺酸基团（-SO3H）取代。这种化合物是一种固体，通常呈白色至淡黄色，是一种重要的有机合成...
To convert benzene to benzoic acid, we can follow a series of chemical reactions. Here’s a step-by-step text solution:Step 1: Bromination of Benzene - Reaction: Benzene (C₆H₆) undergoes bromination in th
The other MUC metabolites tested, CHO/COOH and OH/COOH were weak inhibitors of GJIC whereas COOH/COOH had no effect. Benzene itself had no effect on GJIC when tested in concentrations up to 20mmolL 1 . The relative potency observed for the metabolites on GJIC is similar to their hemato...
In the case of sodium dodecyl sulfate (SDS), at low concentrations (5 mM), which is greater than the critical micellar concentration of SDS in 0.1 M NaCl (1.5 mM at 25°C) [144], the crystals are primarily flower shaped and only few rhombohedral and spherical particles are obtained. Whe...
