(1S)-1-[3-[(2-Methoxyethoxy)methoxy]phenyl]-1,2-ethanediol (S)-1-(3-Methoxyethoxymethoxy)phenyl-1,2-ethanediol 215439-44-4 CAS 215439-44-4

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.

(1S)-1-[3-[(2-Methoxyethoxy)methoxy]phenyl]-1,2-ethanediol (S)-1-(3-Methoxyethoxymethoxy)phenyl-1,2-ethanediol 215439-44-4 (CAS 215439-44-4) is a high-purity analytical reference standard with the molecular formula C12H18O5 and a molecular weight of 242.27 g/mol.

Structurally, (1S)-1-[3-[(2-Methoxyethoxy)methoxy]phenyl]-1,2-ethanediol (S)-1-(3-Methoxyethoxymethoxy)phenyl-1,2-ethanediol 215439-44-4 (C12H18O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 242.27 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).

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.
