ditert-butyl cis-1-methyl-6-oxo-3,3a,5,6a-tetrahydropyrrolo[3,2-c]pyrazole-2,4-dicarboxylate CAS 2597337-27-2 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 ditert-butyl cis-1-methyl-6-oxo-3,3a,5,6a-tetrahydropyrrolo[3,2-c]pyrazole-2,4-dicarboxylate.

ditert-butyl cis-1-methyl-6-oxo-3,3a,5,6a-tetrahydropyrrolo[3,2-c]pyrazole-2,4-dicarboxylate (CAS 2597337-27-2), molecular formula C16H27N3O5 and molecular weight 341.40 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of ditert-butyl cis-1-methyl-6-oxo-3,3a,5,6a-tetrahydropyrrolo[3,2-c]pyrazole-2,4-dicarboxylate (C16H27N3O5) is characterized by a nitrogen-containing heterocyclic scaffold, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), ditert-butyl cis-1-methyl-6-oxo-3,3a,5,6a-tetrahydropyrrolo[3,2-c]pyrazole-2,4-dicarboxylate 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.
