Chemical Structure
Description
The molecular framework of Formaldehyde, polymer with 4-(1,1-dimethylpropyl)phenol and oxirane (C11H16OC2H4OCH2O) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Formaldehyde, polymer with 4-(1,1-dimethylpropyl)phenol and oxirane (CAS 63428-93-3) is a high-purity analytical reference standard with the molecular formula C11H16OC2H4OCH2O and a molecular weight of 238.33 g/mol.
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.
