Chemical Structure

Ethyl 2-((1R,5R)-5-hydroxycyclopent-2-en-1-yl)acetate CAS 298181-33-6 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 Ethyl 2-((1R,5R)-5-hydroxycyclopent-2-en-1-yl)acetate.

Ethyl 2-((1R,5R)-5-hydroxycyclopent-2-en-1-yl)acetate (CAS 298181-33-6) is a high-purity analytical reference standard with the molecular formula C23H38O4Si and a molecular weight of 406.63 g/mol.

The molecular framework of Ethyl 2-((1R,5R)-5-hydroxycyclopent-2-en-1-yl)acetate (C23H38O4Si) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
