Chemical Structure
Description
(S)-α-(2-Amino-5-chlorophenyl)-2,3-dimethoxybenzenemethanol (CAS 189059-58-3) is a high-purity analytical reference standard with the molecular formula C15H16ClNO3 and a molecular weight of 293.75 g/mol.
(S)-α-(2-Amino-5-chlorophenyl)-2,3-dimethoxybenzenemethanol (C15H16ClNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), (S)-α-(2-Amino-5-chlorophenyl)-2,3-dimethoxybenzenemethanol 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.
