Chemical Structure
Description
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.
(2-Chloro-5-fluorophenyl)hydrazine (CAS 737752-10-2), molecular formula C6H6ClFN2 and molecular weight 160.58 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, fluorine/chlorine substitution, an aromatic ring system, (2-Chloro-5-fluorophenyl)hydrazine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 160.58 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).
CATO manufactures (2-Chloro-5-fluorophenyl)hydrazine 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.
