3-{4-chloro-6-methyl-5-phenylthieno[2,3-d]pyrimidin-2-yl}pyridine CAS 851176-00-6

Description

3-{4-chloro-6-methyl-5-phenylthieno[2,3-d]pyrimidin-2-yl}pyridine (C18H12ClN3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

3-{4-chloro-6-methyl-5-phenylthieno[2,3-d]pyrimidin-2-yl}pyridine (CAS 851176-00-6), molecular formula C18H12ClN3S and molecular weight 337.83 g/mol, is a CATO reference standard with documented purity and traceability.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 3-{4-chloro-6-methyl-5-phenylthieno[2,3-d]pyrimidin-2-yl}pyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
