CATO supplies (2S)-2,4,4-Trimethyl-5-oxo-1,2-pyrrolidinedicarboxylic Acid 1-(1,1-Dimethylethyl) 2-Methyl Ester 1217662-00-4 Methyl (2S)-1-tert-Boc-2,4,4-trimethylpyroglutamate (CAS 1217662-00-4), a certified reference material (molecular formula C14H23NO5, MW 285.34 g/mol) for analytical method development and quality control.
Structurally, (2S)-2,4,4-Trimethyl-5-oxo-1,2-pyrrolidinedicarboxylic Acid 1-(1,1-Dimethylethyl) 2-Methyl Ester 1217662-00-4 Methyl (2S)-1-tert-Boc-2,4,4-trimethylpyroglutamate (C14H23NO5) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 285.34 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
