Chemical Structure
Description
4-methoxy-2-methylpyrrolidine-2-carboxylic acid hydrochloride (CAS 2031259-19-3), molecular formula C7H13NO3HCl and molecular weight 195.64 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-methoxy-2-methylpyrrolidine-2-carboxylic acid hydrochloride (C7H13NO3HCl) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 4-methoxy-2-methylpyrrolidine-2-carboxylic acid hydrochloride 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.
