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 1-(2-Chloroethyl)-2-fluorobenzene.
1-(2-Chloroethyl)-2-fluorobenzene (CAS 119779-12-3), molecular formula C8H8ClF and molecular weight 158.60 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(2-Chloroethyl)-2-fluorobenzene (C8H8ClF) is characterized by fluorine/chlorine substitution, an aromatic ring system. 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. 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.
CATO manufactures 1-(2-Chloroethyl)-2-fluorobenzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
