Ethyl 6,6-dimethyl-3-[(2-pyridinylcarbonyl)amino]-5,6-dihydropyrrolo[3,4-c]pyrazole-2(4H)-carboxylate CAS 1041260-92-7

Description

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.

Ethyl 6,6-dimethyl-3-[(2-pyridinylcarbonyl)amino]-5,6-dihydropyrrolo[3,4-c]pyrazole-2(4H)-carboxylate (CAS 1041260-92-7), molecular formula C16H19N5O3 and molecular weight 329.35 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, Ethyl 6,6-dimethyl-3-[(2-pyridinylcarbonyl)amino]-5,6-dihydropyrrolo[3,4-c]pyrazole-2(4H)-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 329.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
