Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1S,2S)-2-fluorocyclopentane-1-carboxylic acid.
(1S,2S)-2-fluorocyclopentane-1-carboxylic acid (CAS 2165871-29-2), molecular formula C6H9FO2 and molecular weight 132.13 g/mol, is a CATO reference standard with documented purity and traceability.
(1S,2S)-2-fluorocyclopentane-1-carboxylic acid (C6H9FO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. 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), (1S,2S)-2-fluorocyclopentane-1-carboxylic 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.
