Chemical Structure
Description
(S)-2-Chloro-3-phenylpropan-1-ol (CAS 127180-75-0) is a high-purity analytical reference standard with the molecular formula C9H11ClO and a molecular weight of 170.64 g/mol.
(S)-2-Chloro-3-phenylpropan-1-ol (C9H11ClO) contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
