2,5-Dichloro-4-(trifluoromethoxy)pyridine CAS 1361495-71-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,5-Dichloro-4-(trifluoromethoxy)pyridine.

2,5-Dichloro-4-(trifluoromethoxy)pyridine (CAS 1361495-71-7), molecular formula C6H2Cl2F3NO and molecular weight 231.99 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 2,5-Dichloro-4-(trifluoromethoxy)pyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.99 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures 2,5-Dichloro-4-(trifluoromethoxy)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.
