2,3,5-Trichlorobenzaldehyde CAS 56961-75-2 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

2,3,5-Trichlorobenzaldehyde (CAS 56961-75-2) is a high-purity analytical reference standard with the molecular formula C7H3Cl3O and a molecular weight of 209.46 g/mol.

2,3,5-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).

CATO manufactures 2,3,5-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.
