Chemical Structure

3-(7-Methyl-3-indolyl)propanoic Acid CAS 33035-77-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 203.24 g/mol gives 3-(7-Methyl-3-indolyl)propanoic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-(7-Methyl-3-indolyl)propanoic Acid (CAS 33035-77-7), molecular formula C12H13NO2 and molecular weight 203.24 g/mol, is a CATO reference standard with documented purity and traceability.

3-(7-Methyl-3-indolyl)propanoic Acid (C12H13NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
