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 (S)-2-(2-Chlorophenyl)-2-hydroxypropionic Acid.
(S)-2-(2-Chlorophenyl)-2-hydroxypropionic Acid (CAS 1215178-12-3) is a high-purity analytical reference standard with the molecular formula C9H9ClO3 and a molecular weight of 200.62 g/mol.
Structurally, (S)-2-(2-Chlorophenyl)-2-hydroxypropionic Acid (C9H9ClO3) 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 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 200.62 g/mol, it falls into the medium-molecular-weight range. 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.
