Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
58041-19-3 1,4-Oxathiin, 2,3-dihydro-5,6-diphenyl- 4-19-00-00390 (Beilstein Handbook Reference) BRN 0207580 2,3-Dihydro-5,6-diphenyl-1,4-oxathiin UBI-P293 (CAS 58041-19-3), molecular formula C16H26OS and molecular weight 266.44 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 58041-19-3 1,4-Oxathiin, 2,3-dihydro-5,6-diphenyl- 4-19-00-00390 (Beilstein Handbook Reference) BRN 0207580 2,3-Dihydro-5,6-diphenyl-1,4-oxathiin UBI-P293 (C16H26OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 266.44 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.
