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 (4-((2,5-Dihydro-1H-pyrrol-1-yl)methyl)phenyl)(o-tolyl)methanone.
CATO supplies (4-((2,5-Dihydro-1H-pyrrol-1-yl)methyl)phenyl)(o-tolyl)methanone (CAS 898763-71-8), a certified reference material (molecular formula C19H19NO, MW 277.36 g/mol) for analytical method development and quality control.
(4-((2,5-Dihydro-1H-pyrrol-1-yl)methyl)phenyl)(o-tolyl)methanone (C19H19NO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
