Description
CATO manufactures 6-Chloro-2-pyridinecarbaldehyde 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.
6-Chloro-2-pyridinecarbaldehyde (CAS 54087-03-5), molecular formula C6H4ClNO and molecular weight 141.56 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-Chloro-2-pyridinecarbaldehyde (C6H4ClNO) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing 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).
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.
