(S)-Propyl 4-ethyl-4-hydroxy-8-methoxy-3-oxo-3,4-dihydro-1H-pyrano[3,4-c]pyridine-6-carboxylate CAS 183434-00-6 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 (S)-Propyl 4-ethyl-4-hydroxy-8-methoxy-3-oxo-3,4-dihydro-1H-pyrano[3,4-c]pyridine-6-carboxylate.

(S)-Propyl 4-ethyl-4-hydroxy-8-methoxy-3-oxo-3,4-dihydro-1H-pyrano[3,4-c]pyridine-6-carboxylate (CAS 183434-00-6), molecular formula C15H19NO6 and molecular weight 309.31 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (S)-Propyl 4-ethyl-4-hydroxy-8-methoxy-3-oxo-3,4-dihydro-1H-pyrano[3,4-c]pyridine-6-carboxylate (C15H19NO6) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.

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.
