(1S)-2-Benzyl-3-oxocyclopentane-1-carboxylic acid CAS 1212741-63-3 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 (1S)-2-Benzyl-3-oxocyclopentane-1-carboxylic acid.

(1S)-2-Benzyl-3-oxocyclopentane-1-carboxylic acid (CAS 1212741-63-3), molecular formula C13H14O3 and molecular weight 218.25 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (1S)-2-Benzyl-3-oxocyclopentane-1-carboxylic acid (C13H14O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 218.25 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

CATO manufactures (1S)-2-Benzyl-3-oxocyclopentane-1-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
