Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,6-Dimethyl-N-[(E)-(4-methylphenyl)methylidene]-3-(1H-pyrrol-1-yl)thieno[2,3-b]pyridine-2-carbohydrazide.
4,6-Dimethyl-N-[(E)-(4-methylphenyl)methylidene]-3-(1H-pyrrol-1-yl)thieno[2,3-b]pyridine-2-carbohydrazide (CAS 478029-11-7) is a high-purity analytical reference standard with the molecular formula C22H20N4OS and a molecular weight of 388.49 g/mol.
4,6-Dimethyl-N-[(E)-(4-methylphenyl)methylidene]-3-(1H-pyrrol-1-yl)thieno[2,3-b]pyridine-2-carbohydrazide (C22H20N4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; 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.
