Chemical Structure
Description
As a certified reference material (CRM), Ethyl Polyester 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.
CATO supplies Ethyl Polyester (CAS 54504-70-0), a certified reference material (molecular formula C19H21ClN4O5, MW 420.85 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Ethyl Polyester is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 420.85 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
