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 5-Chloro-2-(perfluoroethyl)pyridine.
CATO supplies 5-Chloro-2-(perfluoroethyl)pyridine (CAS 1816282-83-3), a certified reference material (molecular formula C7H3ClF5N, MW 231.55 g/mol) for analytical method development and quality control.
Owing to a nitrile group, fluorine/chlorine substitution, an aromatic ring system, 5-Chloro-2-(perfluoroethyl)pyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 5-Chloro-2-(perfluoroethyl)pyridine 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.
