Chemical Structure

(R)-4-((R)-1-hydroxyethyl)-1-((S)-1-(4-methoxyphenyl)ethyl)pyrrolidin-2-one CAS 1809817-07-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (R)-4-((R)-1-hydroxyethyl)-1-((S)-1-(4-methoxyphenyl)ethyl)pyrrolidin-2-one.

(R)-4-((R)-1-hydroxyethyl)-1-((S)-1-(4-methoxyphenyl)ethyl)pyrrolidin-2-one (CAS 1809817-07-9) is a high-purity analytical reference standard with the molecular formula C15H21NO3 and a molecular weight of 263.33 g/mol.

Structurally, (R)-4-((R)-1-hydroxyethyl)-1-((S)-1-(4-methoxyphenyl)ethyl)pyrrolidin-2-one (C15H21NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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 263.33 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.

As a certified reference material (CRM), (R)-4-((R)-1-hydroxyethyl)-1-((S)-1-(4-methoxyphenyl)ethyl)pyrrolidin-2-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
