Description
The occurrence of 939-87-7 Cyclopropanecarbonyl chloride, 2-phenyl-, trans- (8CI)(9CI) Cyclopropanecarbonyl chloride, 2-phenyl-, (E)- trans-2-Phenylcyclopropanecarbonyl chloride EINECS 213-365-8 NSC 80667 trans-2-Phenylcyclopropane-1-carboxylic acid chloride is closely related to a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 939-87-7 Cyclopropanecarbonyl chloride, 2-phenyl-, trans- (8CI)(9CI) Cyclopropanecarbonyl chloride, 2-phenyl-, (E)- trans-2-Phenylcyclopropanecarbonyl chloride EINECS 213-365-8 NSC 80667 trans-2-Phenylcyclopropane-1-carboxylic acid chloride (CAS 939-87-7), a certified reference material (molecular formula C10H15ClO, MW 186.68 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H15ClO, 939-87-7 Cyclopropanecarbonyl chloride, 2-phenyl-, trans- (8CI)(9CI) Cyclopropanecarbonyl chloride, 2-phenyl-, (E)- trans-2-Phenylcyclopropanecarbonyl chloride EINECS 213-365-8 NSC 80667 trans-2-Phenylcyclopropane-1-carboxylic acid chloride contains a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 186.68 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
