Chemical Structure
Description
As a certified reference material (CRM), 3-methyl-5,6-dihydro-1H-pyrrolo[3,4-c]pyrazol-4-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.
3-methyl-5,6-dihydro-1H-pyrrolo[3,4-c]pyrazol-4-one (CAS 82036-25-7) is a high-purity analytical reference standard with the molecular formula C6H7N3O and a molecular weight of 137.14 g/mol.
Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, 3-methyl-5,6-dihydro-1H-pyrrolo[3,4-c]pyrazol-4-one is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 137.14 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).
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.
