Chemical Structure
Description
The occurrence of 2,2-Dihydroxy-3,3,3-trichloropropionic acid is closely related to a carboxylic acid group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,2-Dihydroxy-3,3,3-trichloropropionic acid (CAS 73257-73-5), a certified reference material (molecular formula C3H3Cl3O4, MW 209.41 g/mol) for analytical method development and quality control.
2,2-Dihydroxy-3,3,3-trichloropropionic acid (C3H3Cl3O4) contains a carboxylic acid group, an ether linkage, chlorine substitution. 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.
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.
