α-Hydroxyhippuric acid, also known as α-hydroxybenzeneacetic acid or AHH, is an organic compound with the chemical formula C8H8O4. It is a derivative of hippuric acid, which is a conjugate of glycine and benzoic acid. AHH is formed as a result of the metabolism of aromatic compounds, particularly benzoic acid, in the human body. It is used as a urinary biomarker for exposure to aromatic compounds, such as toluene and benzene, which are commonly found in solvents and fuels. The presence of elevated levels of α-hydroxyhippuric acid in urine can indicate exposure to these harmful substances, making it a valuable tool in occupational and environmental health assessments.

19791-95-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 19791-95-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,7,9 and 1 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 19791-95:
(7*1)+(6*9)+(5*7)+(4*9)+(3*1)+(2*9)+(1*5)=158
158 % 10 = 8
So 19791-95-8 is a valid CAS Registry Number.

Methods for the synthesis of dicarba bridges in organic compounds

-

Page/Page column 25; 121, (2015/11/17)

The present invention relates to methods for forming dicarba bridges in organic compounds. This involves the use of a pair of complementary metathesisable groups on the organic compound, and subjecting the compound to cross-metathesis under microwave radiation conditions. In an alternative, the compounds contain a turn-inducing group between the pair of cross-metathesisable groups to facilitate the cross-metathesis.

Investigations on the synthesis and chemiluminescence of novel 2-coumaranones

Schramm, Stefan,Weiss, Dieter,Navizet, Isabelle,Roca-Sanjuan, Daniel,Brandl, Herbert,Beckert, Rainer,Goerls, Helmar

, p. 174 - 188 (2013/06/27)

Optimized syntheses of 2-coumaranone derivatives and, based thereon, several new representatives of this class of substances are described. They show a clearly visible chemiluminescence under the exposure of a strong base and in the presence of oxygen. The wavelength and intensity of the light emitted depends on both the substituents on the benzo annealed, as well as on the type of base used. A mechanism is presented in which a delocalized enolate is postulated as a key intermediate. ARKAT-USA, Inc.

Hydrogen tunneling in peptidylglycine α-hydroxylating monooxygenase

Francisco, Wilson A.,Knapp, Michael J.,Blackburn, Ninian J.,Klinman, Judith P.

, p. 8194 - 8195 (2007/10/03)

The temperature dependence of the primary and secondary intrinsic isotope effects for the C-H bond cleavage catalyzed by peptidylglycine α-hydroxylating monooxygenase has been determined. Analysis of the magnitude and Arrhenius behavior of the intrinsic isotope effects provides strong evidence for the use of tunneling as a primary catalytic strategy for this enzyme. Modeling of the isotope effect data allows for a comparison to the hydrogen transfer catalyzed by soybean lipoxygenase in terms of environmental reorganization energy and frequency of the protein vibration that controls the hydrogen transfer.
