Description
29706-96-5 Resistoflavin 2H-Benzo(cd)pyrene-2,6,10(1H,11bH)-trione, 3,5,7,11b-tetrahydroxy-1,1,9-trimethyl-, (-)- (-)-3,5,7,11b-Tetrahydroxy-1,1,9-trimethyl-2H-benzo(cd)pyrene-2,6,10(1H,11bH)-trione BRN 2491848 Resistoflavine (CAS 29706-96-5), molecular formula C22H16O7 and molecular weight 392.36 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 29706-96-5 Resistoflavin 2H-Benzo(cd)pyrene-2,6,10(1H,11bH)-trione, 3,5,7,11b-tetrahydroxy-1,1,9-trimethyl-, (-)- (-)-3,5,7,11b-Tetrahydroxy-1,1,9-trimethyl-2H-benzo(cd)pyrene-2,6,10(1H,11bH)-trione BRN 2491848 Resistoflavine (C22H16O7) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 392.36 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
