Chemical Structure
Description
(R)-2-Chloro-1-(2,4,5-trimethylphenyl)ethan-1-ol (CAS 1176575-44-2) is a high-purity analytical reference standard with the molecular formula C11H15ClO and a molecular weight of 198.69 g/mol.
The molecular framework of (R)-2-Chloro-1-(2,4,5-trimethylphenyl)ethan-1-ol (C11H15ClO) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (R)-2-Chloro-1-(2,4,5-trimethylphenyl)ethan-1-ol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
