1-Isobutyl-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole-3-carboxylic acid (cas: 146436-31-9) belongs to indole derivatives. The indole subunit is an almost ubiquitous component of biologically active natural products, and its study has been the focus of research for decades. They are capable of binding to a variety of receptors with high affinity and thus have applications in a wide range of therapeutic areas.Quality Control of 1-Isobutyl-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole-3-carboxylic acid

Separation and characterization of 1,2,3,4-tetrahydro-β-carboline-3-carboxylic acids by HPLC and GC-MS. Identification in wine samples was written by Herraiz, Tomas;Ough, C. S.. And the article was included in American Journal of Enology and Viticulture in 1994.Quality Control of 1-Isobutyl-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole-3-carboxylic acid The following contents are mentioned in the article:

1,2,3,4-Tetrahydro-β-carboline-3-carboxylic acids, products of the reaction of tryptophan and aldehydes in alc. fermented beverages, were isolated by solid phase extraction, analyzed by HPLC, and identified by gas chromatog. and mass spectrometry after derivatization to form N-trifluoroacetyl-1,2,3,4-tetrahydro-β-carboline-3-carboxylic acid Me esters. 1,2,3,4-Tetrahydro-β-carboline-3-carboxylic acid (THCA) and 1-methyl-1,2,3,4-tetrahydro-β-carboline-3-carboxylic acid (both diastereoisomers) were pos. identified in wine samples. 1-Ethyl-1,2,3,4-tetrahydro-β-carboline-3-carboxylic acid (ETCA) and 1-isobutyl-1,2,3,4-tetrahydro-β-carboline-3-carboxylic acid (IBTCA) were not identified in the wines studied. This study involved multiple reactions and reactants, such as 1-Isobutyl-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole-3-carboxylic acid (cas: 146436-31-9Quality Control of 1-Isobutyl-2,3,4,9-tetrahydro-1H-pyrido[3,4-b]indole-3-carboxylic acid).
