Use of 3-methyl-2-benzothiazolone hydrazone in an automated colorimetric method for determination of triglycerides in plasma or serum.
for the determination of serum or plasma triglycerides. The samples are extracted with 2propanol containing activated alumina. An AutoAnalyzer Sampler II and Proportioning Pump II are used in combination with a Gilford Model 300 N spectrophotometer and Model 3091-A debubbler flow cell. Following on-line saponification, glycerol is oxidatively cleaved with sodium metaperiodate. The resulting for...
متن کاملSpectrophotometric determination of pyridoxal and pyridoxal 5'-phosphate with 3-methyl-2-benzothiazolone hydrazone hydrochloride, and their selective assay.
A spectrophotometric method with 3-methyl-2-benzothiazolone hydrazone hydrochloride was developed for the determination of pyridoxal and pyridoxal 5'-phosphate, and for the selective determination of each in the presence of the other. Pyridoxal and pyridoxal 5'-phosphate react with the reagent to yield the azine derivatives, which give characteristic absorption spectra. The highest extinction v...
متن کاملShort Note ( E ) - 3 - Methyl - 6 - ( 3 - oxo - 3 - ( thiophen - 2 - yl ) - 1 - propenyl ) - 2 ( 3 H ) - benzothiazolone
The title compound, (E)-3-methyl-6-(3-oxo-3-(thiophen-2-yl)-1-propenyl)-2(3H)-benzothiazolone, was synthesized by Claisen-Schmidt condensation of 3-methyl-2(3H)-benzothiazolone-6-carbaldehyde with 2-acetylthiophene in 94% yield. The structure of the target compound was confirmed using 1H-NMR, 13C-NMR, IR, MS, and elemental analysis.

The title compound, C(15)H(12)F(3)NO, is a Schiff base which adopts the phenol-imine tautomeric form in the solid state. The dihedral angle between the aromatic rings is 38.79 (5)°. The mol-ecular structure is stabilized by an intra-molecular O-H⋯N hydrogen bond, which generates an S(6) ring. In addition, there is an intra-molecular short C-H⋯F contact.
