Benzoic acid, 2-hydroxy-, reaction products with benzyl alc., bisphenol A-epichlorohydrin polymer and 4,4'-methylenebis[benzenamine] (CAS 68988-23-8), molecular formula C15H16O2C13H14N2C7H6O3C7H8OC3H5ClO and molecular weight 765.34 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Benzoic acid, 2-hydroxy-, reaction products with benzyl alc., bisphenol A-epichlorohydrin polymer and 4,4'-methylenebis[benzenamine] (C15H16O2C13H14N2C7H6O3C7H8OC3H5ClO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 22.0, corresponding to approximately 22 ring(s) or double-bond equivalent(s). With a molecular weight of 765.34 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), Benzoic acid, 2-hydroxy-, reaction products with benzyl alc., bisphenol A-epichlorohydrin polymer and 4,4'-methylenebis[benzenamine] 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.
