Chemical Structure
Description
The occurrence of 4,4'-Dihydroxy-3,3'-di-(hydroxymethyl)diphenylmethane is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4,4'-Dihydroxy-3,3'-di-(hydroxymethyl)diphenylmethane (CAS 2346-44-3), molecular formula C15H16O4 and molecular weight 260.29 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4,4'-Dihydroxy-3,3'-di-(hydroxymethyl)diphenylmethane (C15H16O4) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 260.29 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
