Chemical Structure

Trimethylphloroglucinol CAS 4463-03-0 chemical structure

Description

Trimethylphloroglucinol (CAS 4463-03-0), molecular formula C9H12O3 and molecular weight 168.19 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Trimethylphloroglucinol (C9H12O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 168.19 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.
