(S)-1-benzyl-5-(chloromethyl)pyrrolidin-2-one CAS 1272755-05-1

Description

The occurrence of (S)-1-benzyl-5-(chloromethyl)pyrrolidin-2-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(S)-1-benzyl-5-(chloromethyl)pyrrolidin-2-one (CAS 1272755-05-1), molecular formula C12H14ClNO and molecular weight 223.70 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (S)-1-benzyl-5-(chloromethyl)pyrrolidin-2-one (C12H14ClNO) 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 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 223.70 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
