Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Thalidomide-O-amido-PEG4-C2-NH2 (hydrochloride).
CATO supplies Thalidomide-O-amido-PEG4-C2-NH2 (hydrochloride) (CAS 2245697-85-0), a certified reference material (molecular formula C25H34N4O10HCl, MW 587.02 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, Thalidomide-O-amido-PEG4-C2-NH2 (hydrochloride) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 587.02 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
