Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 194.27 g/mol gives (2,3,5,6-Tetramethyl-1,4-phenylene)dimethanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (2,3,5,6-Tetramethyl-1,4-phenylene)dimethanol (CAS 7522-62-5), a certified reference material (molecular formula C12H18O2, MW 194.27 g/mol) for analytical method development and quality control.
Structurally, (2,3,5,6-Tetramethyl-1,4-phenylene)dimethanol (C12H18O2) 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 194.27 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
