Ethyl 6-chloro-3,4-dimethylthieno[2,3-b]pyridine-2-carboxylate CAS 923738-50-5

Description

The occurrence of Ethyl 6-chloro-3,4-dimethylthieno[2,3-b]pyridine-2-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 6-chloro-3,4-dimethylthieno[2,3-b]pyridine-2-carboxylate (CAS 923738-50-5) is a high-purity analytical reference standard with the molecular formula C12H12ClNO2S and a molecular weight of 269.75 g/mol.

Structurally, Ethyl 6-chloro-3,4-dimethylthieno[2,3-b]pyridine-2-carboxylate (C12H12ClNO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 269.75 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
