Chemical Structure

4-O-Methyl-TPA CAS 57716-89-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 630.85 g/mol gives 4-O-Methyl-TPA distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-O-Methyl-TPA (CAS 57716-89-9) is a high-purity analytical reference standard with the molecular formula C37H58O8 and a molecular weight of 630.85 g/mol.

Structurally, 4-O-Methyl-TPA (C37H58O8) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 630.85 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).

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.
