Chemical Structure
Description
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.
CATO supplies 2-Propenoic acid, 2-methyl-, polymer with 1,3-butadiene, ethenylbenzene and 2-propenoic acid (CAS 26603-97-4), a certified reference material (molecular formula C8H8C4H6O2C3H4O2C4H6, MW 316.40 g/mol) for analytical method development and quality control.
The molecular framework of 2-Propenoic acid, 2-methyl-, polymer with 1,3-butadiene, ethenylbenzene and 2-propenoic acid (C8H8C4H6O2C3H4O2C4H6) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. 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 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.
