Chemical Structure
Description
As a certified reference material (CRM), Chlorofluoromethane 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.
Chlorofluoromethane (CAS 593-70-4), molecular formula CH2ClF and molecular weight 68.48 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Chlorofluoromethane (CH2ClF) is characterized by fluorine/chlorine 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.
