Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

(1S,​1''S)​-3,​3''-​[Oxybis(methylene)​]​bis-​[1,​1'-​binaphthalene]​-​2,​2'-​diol (CAS 336800-79-4) is a high-purity analytical reference standard with the molecular formula C42H30O5 and a molecular weight of 614.68 g/mol.

Structurally, (1S,​1''S)​-3,​3''-​[Oxybis(methylene)​]​bis-​[1,​1'-​binaphthalene]​-​2,​2'-​diol (C42H30O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 28.0, corresponding to approximately 28 ring(s) or double-bond equivalent(s). With a molecular weight of 614.68 g/mol, it falls into the 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).

As a certified reference material (CRM), (1S,​1''S)​-3,​3''-​[Oxybis(methylene)​]​bis-​[1,​1'-​binaphthalene]​-​2,​2'-​diol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
