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 (2,2-Dichloro-1-fluorocyclopropyl)benzene.
CATO supplies (2,2-Dichloro-1-fluorocyclopropyl)benzene (CAS 502763-69-1), a certified reference material (molecular formula C9H7Cl2F, MW 205.06 g/mol) for analytical method development and quality control.
(2,2-Dichloro-1-fluorocyclopropyl)benzene (C9H7Cl2F) contains fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), (2,2-Dichloro-1-fluorocyclopropyl)benzene 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.
