Chemical Structure

5-(Perfluoroethyl)picolinaldehyde CAS 1816285-55-8 chemical structure

Description

The occurrence of 5-(Perfluoroethyl)picolinaldehyde is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-(Perfluoroethyl)picolinaldehyde (CAS 1816285-55-8), molecular formula C8H4F5NO and molecular weight 225.12 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5-(Perfluoroethyl)picolinaldehyde (C8H4F5NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 225.12 g/mol, it falls into the medium-molecular-weight range. 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 5-(Perfluoroethyl)picolinaldehyde 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.
