Chemical Structure
Description
(4-Chloro-3-fluorophenyl)(cyclopentyl)methanol (CAS 1340539-90-3), molecular formula C12H14ClFO and molecular weight 228.69 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H14ClFO, (4-Chloro-3-fluorophenyl)(cyclopentyl)methanol contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 228.69 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
