Chemical Structure
Description
The occurrence of (2R)-3-chloro-2-hydroxy-propanoic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2R)-3-chloro-2-hydroxy-propanoic acid (CAS 61505-41-7), molecular formula C3H5ClO3 and molecular weight 124.52 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C3H5ClO3, (2R)-3-chloro-2-hydroxy-propanoic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 124.52 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
