Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 192.00 g/mol gives Clopyralid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Clopyralid (CAS 1702-17-6), a certified reference material (molecular formula C6H3Cl2NO2, MW 192.00 g/mol) for analytical method development and quality control.
Clopyralid (C6H3Cl2NO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Clopyralid 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.
