Chemical Structure
Description
Owing to an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, (S)-Thalidomide is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 749.89 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
(S)-Thalidomide (CAS 841-67-8), molecular formula C36H68F4NO8P and molecular weight 749.89 g/mol, is a CATO reference standard with documented purity and traceability.
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.
