Colorimetric method for hippuric acid.
FTIPPURIC ACID 1S an important metabolic product normally present in urine in amounts determined by tile ingestion of benzyl-containing foods and medicinals (ii). Because this compound is comparatively inert chemically, identification requires isolation and the determination of physical constants after extensive purification. There has long been need for a reliable and sensitive color reaction ...
متن کاملSome Modifications of the Picric Acid Method for Sugars
The writers recently had occasion to use the picric acid colorimetric method (commonly called the Benedict-Lewis method) 2 for determining the sugars in cornstalk juices. Although it has been used mostly as a micro method for blood and urine analyses, it has been used to some extent as a macro method. {3* 5, 12.) It proved to be more rapid than, and approximately as accurate as a, copper reduct...
متن کاملOrphenadrinium picrate picric acid
The asymmetric unit of the title compound N,N-dimethyl-2-[(2-methyl-phen-yl)phenyl-meth-oxy]ethanaminium picrate picric acid, C(18)H(24)NO(+)·C(6)H(2)N(3)O(7) (-)·C(6)H(3)N(3)O(7), contains one orphenadrinium cation, one picrate anion and one picric acid mol-ecule. In the orphenadrine cation, the two aromatic rings form a dihedral angle of 70.30 (7)°. There is an intra-molecular O-H⋯O hydrogen ...
متن کاملpKa Modulation in rhodamine based probes for colorimetric detection of picric acid.
Tuning the pKa in acid sensitive rhodamine spirolactam derivatives as a function of the solvent medium resulted in the selective detection of picric acid from its lower nitro phenolic analogues and a few other carboxylic acids.
متن کاملAn automated colorimetric method for determining oxalic acid in plant material.
A simple, automated colorimetric method for determining oxalic acid in plant material is based on the quantitative reduction in colour of a zirconium/3,4-dihydroxyazobenzene-2'-carboxylic.acid complex by microgram quantities of oxaIic acid. I t is suitable for use over a wide range of oxalic acid concentrations. Interference from phosphate, sulphate, citric acid and malic acid was encountered b...
