Description

As a certified reference material (CRM), 6,6'-Methylenebis(2-(2-hydroxy-5-methylbenzyl)-4-methylphenol) 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.

6,6'-Methylenebis(2-(2-hydroxy-5-methylbenzyl)-4-methylphenol) (CAS 20837-68-7), molecular formula C31H32O4 and molecular weight 468.58 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 6,6'-Methylenebis(2-(2-hydroxy-5-methylbenzyl)-4-methylphenol) (C31H32O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 468.58 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
