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 tert-butyl 6-oxo-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-4,5-dihydropyrrolo[3,4-b]pyrrole-1-carboxylate.
tert-butyl 6-oxo-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-4,5-dihydropyrrolo[3,4-b]pyrrole-1-carboxylate (CAS 2052290-73-8), molecular formula C17H29BN2O5 and molecular weight 352.23 g/mol, is a CATO reference standard with documented purity and traceability.
tert-butyl 6-oxo-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-4,5-dihydropyrrolo[3,4-b]pyrrole-1-carboxylate (C17H29BN2O5) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
