5,5',5'',5'''-Methanetetrayltetrakis(2-hydroxybenzaldehyde) CAS 1352523-65-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 496.46 g/mol gives 5,5',5'',5'''-Methanetetrayltetrakis(2-hydroxybenzaldehyde) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5,5',5'',5'''-Methanetetrayltetrakis(2-hydroxybenzaldehyde) (CAS 1352523-65-9), molecular formula C29H20O8 and molecular weight 496.46 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 5,5',5'',5'''-Methanetetrayltetrakis(2-hydroxybenzaldehyde) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 496.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
