Chemical Structure
Description
Poly[2-methoxy-5-(3,7-dimethyloctyloxy)-1,4-phenylenevinylene] (C21H34O2N) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO supplies Poly[2-methoxy-5-(3,7-dimethyloctyloxy)-1,4-phenylenevinylene] (CAS 177716-59-5), a certified reference material (molecular formula C21H34O2N, MW 332.51 g/mol) for analytical method development and quality control.
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.
