Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 335.28 g/mol gives Trifluralin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Trifluralin (CAS 1582-09-8) is a high-purity analytical reference standard with the molecular formula C13H16F3N3O4 and a molecular weight of 335.28 g/mol.
Trifluralin (C13H16F3N3O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, 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.
As a certified reference material (CRM), Trifluralin meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
