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 tert-Butyl 4,5-dihydrothieno[2,3-c]pyridine-6(7H)-carboxylate.
tert-Butyl 4,5-dihydrothieno[2,3-c]pyridine-6(7H)-carboxylate (CAS 165947-52-4) is a high-purity analytical reference standard with the molecular formula C12H17NO2S and a molecular weight of 239.33 g/mol.
The molecular framework of tert-Butyl 4,5-dihydrothieno[2,3-c]pyridine-6(7H)-carboxylate (C12H17NO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, 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.
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.
