In the structure of the title compound, C(8)H(12)NO(+)·C(7)H(5)O(6)S(-)·H(2)O, isolated from the reaction of 2-(4-amino-phen-yl)ethanol with 5-sulfosalicylic acid, the cations form head-to-tail hydrogen-bonded chains through C(1) (1)(9) anilinium N(+)-H⋯O(hydrox-yl) inter-actions while the anions also form parallel but C(1) (1)(8)-linked chains through carboxylic acid O-H⋯O(sulfonate) inter-act...

Cocrystallization of 1-hydroxy-ethyl-2-methyl-5-nitroimidazole (metronidazole) and 5-sulfosalicylic acid (5-H(2)SSA) from methanol solution yields the title salt, C(6)H(10)N(3)O(3) (+)·C(7)H(5)O(6)S(-). In the crystal structure, the ions are linked by a combination of inter-molecular O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional framework. The hydroxyl group of the cation i...

The identity of the enzyme urease with the octahedral globulin crystals isolated by the senior author from the jack bean in 1926 (1) has been challenged by Waldschmidt-Leitz and Steigerwaldt (2). These investigators published a paper in which they claimed that crystalline urease is not inactivated at pH 7.0 by incubation with trypsin or papain, while the protein component of the urease undergoe...

A novel kind of organic-inorganic monomer SUASi has been achieved by modifying 5-sulfosalicylic acid (SUA) with 3-aminopropyltrimethoxysilane (APS), subsequently binary and ternary Eu3+ mesoporous hybrid materials with 5-sulfosalicylic acid (SUA)-functionalized SBA-15 and 1,10-phenanthroline (phen) are synthesized by co-condensation of SUASi and TEOS in the presence of Eu3+ complex and Pluronic...

Background: Proteinuria indicates a kidney disorder and provides important prognostic information in diagnosing disease. To determine the presence of protein urine, urinalysis examination is carried out. generally uses heating method with acetic acid, sulfosalicylic concentrated nitric acid as reagents. In Indonesia, use for proteinuria still primary choice. An alternative reagent needed that c...

Inter-laboratory surveys have shown that "routine methods" of urinary protein determination are often unsatisfactory. Therefore, we compared six frequently used methods for determination of protein in urine with respect to linearity, within-batch and between-batch precision, comparative bias, and practicability. We assayed dilutions of human and bovine albumin and serum, and fresh and lyophiliz...

Variation of the protein content in urine of patients known to excrete protein in excessiveamountswas studied. Variation in different specimensobtained from the same patient on a particular day and from day to day were studied. A total of 293 urine specimensexcreted over a 3to 6-day period by 25 patients were examined. No particular pattern of protein excretion was observed. The morning specime...
