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.
Lactofen (CAS 77501-63-4) is a high-purity analytical reference standard with the molecular formula C19H15ClF3NO7 and a molecular weight of 461.77 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, Lactofen is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 461.77 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), Lactofen 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.
