Chemical Structure

2-(Ethylthio)spiro[3.5]nonane-2-carboxylic acid CAS 1491122-96-3 chemical structure

Description

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.

2-(Ethylthio)spiro[3.5]nonane-2-carboxylic acid (CAS 1491122-96-3) is a high-purity analytical reference standard with the molecular formula C12H20O2S and a molecular weight of 228.35 g/mol.

The molecular framework of 2-(Ethylthio)spiro[3.5]nonane-2-carboxylic acid (C12H20O2S) is characterized by a sulfone group, a carboxylic acid group, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
