Chemical Structure

1,1,3,3-Tetramethyl-2,3,3a,4-tetrahydrocyclopenta[c]pyrrol-5(1H)-one CAS 104668-23-7 chemical structure

Description

1,1,3,3-Tetramethyl-2,3,3a,4-tetrahydrocyclopenta[c]pyrrol-5(1H)-one (CAS 104668-23-7), molecular formula C11H17NO and molecular weight 179.26 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1,1,3,3-Tetramethyl-2,3,3a,4-tetrahydrocyclopenta[c]pyrrol-5(1H)-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 179.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), 1,1,3,3-Tetramethyl-2,3,3a,4-tetrahydrocyclopenta[c]pyrrol-5(1H)-one 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.
