Chemical Structure
Description
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.
CATO supplies 2,5-Dimethyl-4,6-diphenyl-1,2,3,5-tetrahydropyrrolo[3,4-c]pyrrole (CAS 400085-71-4), a certified reference material (molecular formula C20H20N2, MW 288.39 g/mol) for analytical method development and quality control.
Structurally, 2,5-Dimethyl-4,6-diphenyl-1,2,3,5-tetrahydropyrrolo[3,4-c]pyrrole (C20H20N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 288.39 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
