Chemical Structure

(S)-1-(2-Chlorophenyl)-1,2-ethanediol CAS 133082-13-0 chemical structure

Description

The occurrence of (S)-1-(2-Chlorophenyl)-1,2-ethanediol is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (S)-1-(2-Chlorophenyl)-1,2-ethanediol (CAS 133082-13-0), a certified reference material (molecular formula C8H9ClO2, MW 172.61 g/mol) for analytical method development and quality control.

Structurally, (S)-1-(2-Chlorophenyl)-1,2-ethanediol (C8H9ClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 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 172.61 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
