Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ald-Ph-amido-PEG4-propargyl.
Ald-Ph-amido-PEG4-propargyl (CAS 1969299-27-1), molecular formula C19H25NO6 and molecular weight 363.40 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Ald-Ph-amido-PEG4-propargyl is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 363.40 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.
As a certified reference material (CRM), Ald-Ph-amido-PEG4-propargyl 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.
