Chemical Structure
Description
The occurrence of (R)-2-(2-Chlorophenyl)-2-hydroxypropionic Acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(R)-2-(2-Chlorophenyl)-2-hydroxypropionic Acid (CAS 1215178-13-4), molecular formula C9H9ClO3 and molecular weight 200.62 g/mol, is a CATO reference standard with documented purity and traceability.
(R)-2-(2-Chlorophenyl)-2-hydroxypropionic Acid (C9H9ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
As a certified reference material (CRM), (R)-2-(2-Chlorophenyl)-2-hydroxypropionic Acid 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.
