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 (2S)-4-Bromo-2-methylpyrrolidine-2-carboxylic butyric anhydride.
(2S)-4-Bromo-2-methylpyrrolidine-2-carboxylic butyric anhydride (CAS 64969-78-4), molecular formula C8H15BrO2 and molecular weight 223.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2S)-4-Bromo-2-methylpyrrolidine-2-carboxylic butyric anhydride (C8H15BrO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (2S)-4-Bromo-2-methylpyrrolidine-2-carboxylic butyric anhydride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
