3-(3-Chlorophenyl)-1-(3-methylpyridin-2-yl)pyrrolidine-2,5-dione CAS 132458-99-2

Description

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.

3-(3-Chlorophenyl)-1-(3-methylpyridin-2-yl)pyrrolidine-2,5-dione (CAS 132458-99-2), molecular formula C16H13ClN2O2 and molecular weight 300.74 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-(3-Chlorophenyl)-1-(3-methylpyridin-2-yl)pyrrolidine-2,5-dione (C16H13ClN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 300.74 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
