Chemical Structure

(1S,2R)-1-ethyl-2-fluorocyclopropane-1-carboxylic acid CAS 1706439-30-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 132.13 g/mol gives (1S,2R)-1-ethyl-2-fluorocyclopropane-1-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (1S,2R)-1-ethyl-2-fluorocyclopropane-1-carboxylic acid (CAS 1706439-30-6), a certified reference material (molecular formula C6H9FO2, MW 132.13 g/mol) for analytical method development and quality control.

The molecular framework of (1S,2R)-1-ethyl-2-fluorocyclopropane-1-carboxylic acid (C6H9FO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
