5-Methoxy-3-(methyl-d3)-indole-2-carboxylic Acid CAS 1794752-91-2

Description

Compared with other compounds in its class, the molecular weight of 208.23 g/mol gives 5-Methoxy-3-(methyl-d3)-indole-2-carboxylic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Methoxy-3-(methyl-d3)-indole-2-carboxylic Acid (CAS 1794752-91-2), molecular formula C11H8D3NO3 and molecular weight 208.23 g/mol, is a CATO reference standard with documented purity and traceability.

5-Methoxy-3-(methyl-d3)-indole-2-carboxylic Acid (C11H8D3NO3) contains deuterium isotope labeling, an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
