Chemical Structure
Description
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.
Spiro[2H-indene-2,3'-[3H]pyrrolo[2,3-b]pyridin]-2'(1'H)-one, 5-amino-1,3-dihydro-, (2S)- (CAS 939016-97-4) is a high-purity analytical reference standard with the molecular formula C15H13N3O and a molecular weight of 251.28 g/mol.
Spiro[2H-indene-2,3'-[3H]pyrrolo[2,3-b]pyridin]-2'(1'H)-one, 5-amino-1,3-dihydro-, (2S)- (C15H13N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
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.
