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 2-Hydroxytetrahydrocyclopenta[c]pyrrole-1,3(2H,3aH)-dione.
2-Hydroxytetrahydrocyclopenta[c]pyrrole-1,3(2H,3aH)-dione (CAS 412283-61-5) is a high-purity analytical reference standard with the molecular formula C7H9NO3 and a molecular weight of 155.15 g/mol.
The molecular framework of 2-Hydroxytetrahydrocyclopenta[c]pyrrole-1,3(2H,3aH)-dione (C7H9NO3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
