Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
7-(2,6-Dimethylphenyl)-2,5,6-trimethyl-3H-pyrrolo[2,3-d]pyrimidin-4(7H)-one (CAS 157286-67-4) is a high-purity analytical reference standard with the molecular formula C17H19N3O and a molecular weight of 281.35 g/mol.
Structurally, 7-(2,6-Dimethylphenyl)-2,5,6-trimethyl-3H-pyrrolo[2,3-d]pyrimidin-4(7H)-one (C17H19N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 281.35 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.
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.
