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 (R)-1-(3,5-Dichlorophenyl)ethan-1-ol.
(R)-1-(3,5-Dichlorophenyl)ethan-1-ol (CAS 1629065-91-3), molecular formula C8H8Cl2O and molecular weight 191.05 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (R)-1-(3,5-Dichlorophenyl)ethan-1-ol (C8H8Cl2O) is characterized by a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
