3-(Indoline-1-carbonyl)-1,2,2-trimethylcyclopentane-1-carboxylic acid CAS 294656-72-7

Description

The occurrence of 3-(Indoline-1-carbonyl)-1,2,2-trimethylcyclopentane-1-carboxylic acid is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(Indoline-1-carbonyl)-1,2,2-trimethylcyclopentane-1-carboxylic acid (CAS 294656-72-7), molecular formula C18H23NO3 and molecular weight 301.38 g/mol, is a CATO reference standard with documented purity and traceability.

3-(Indoline-1-carbonyl)-1,2,2-trimethylcyclopentane-1-carboxylic acid (C18H23NO3) contains a steroid core, 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.
