Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Benzylidene-6-((5-methylfuran-2-yl)methylene)cyclohexanone.
CATO supplies 2-Benzylidene-6-((5-methylfuran-2-yl)methylene)cyclohexanone (CAS 880098-64-6), a certified reference material (molecular formula C19H18O2, MW 278.35 g/mol) for analytical method development and quality control.
2-Benzylidene-6-((5-methylfuran-2-yl)methylene)cyclohexanone (C19H18O2) contains a steroid core, 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. 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.
