Description

Compared with other compounds in its class, the molecular weight of 209.24 g/mol gives rel-(1R,2R)-2'-oxospiro[cyclopropane-2,3'-indoline]-1-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

rel-(1R,2R)-2'-oxospiro[cyclopropane-2,3'-indoline]-1-carboxylic acid (CAS 926667-78-9) is a high-purity analytical reference standard with the molecular formula C11H15NO3 and a molecular weight of 209.24 g/mol.

rel-(1R,2R)-2'-oxospiro[cyclopropane-2,3'-indoline]-1-carboxylic acid (C11H15NO3) contains 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
