Description
121055-10-5 Sdz pco 400 2H-1-Benzopyran-6-carbonitrile, 3,4-dihydro-3-hydroxy-2,2-dimethyl-4-((3-oxo-1-cyclopenten-1-yl)oxy)- (3S-trans)- 3,4-Dihydro-3-hydroxy-2,2-dimethyl-4-(3-oxo-cyclopent-1-enyloxy)-2H-1-benzopyran-6-carbonitrile Sdz pco-400 (CAS 121055-10-5) is a high-purity analytical reference standard with the molecular formula C17H17NO4 and a molecular weight of 299.32 g/mol.
Structurally, 121055-10-5 Sdz pco 400 2H-1-Benzopyran-6-carbonitrile, 3,4-dihydro-3-hydroxy-2,2-dimethyl-4-((3-oxo-1-cyclopenten-1-yl)oxy)- (3S-trans)- 3,4-Dihydro-3-hydroxy-2,2-dimethyl-4-(3-oxo-cyclopent-1-enyloxy)-2H-1-benzopyran-6-carbonitrile Sdz pco-400 (C17H17NO4) contains a flavonoid 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 299.32 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
