Chemical Structure
Description
CATO supplies 3,4,5-Trichlorobenzaldehyde (CAS 56961-76-3), a certified reference material (molecular formula C7H3Cl3O, MW 209.46 g/mol) for analytical method development and quality control.
3,4,5-Trichlorobenzaldehyde (C7H3Cl3O) contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures 3,4,5-Trichlorobenzaldehyde 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.
