Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 152.58 g/mol gives 2-(Chloromethoxy)acetic Acid Ethyl Ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-(Chloromethoxy)acetic Acid Ethyl Ester (CAS 124186-08-9), a certified reference material (molecular formula C5H9ClO3, MW 152.58 g/mol) for analytical method development and quality control.
2-(Chloromethoxy)acetic Acid Ethyl Ester (C5H9ClO3) contains a carboxylic acid group, a hydroxyl 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.
