5-Chloro-9,10-dimethyl-8H-thieno[2',3':4,5]pyrimido[2,1-a]phthalazin-8-one CAS 315676-39-2

Description

The occurrence of 5-Chloro-9,10-dimethyl-8H-thieno[2',3':4,5]pyrimido[2,1-a]phthalazin-8-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Chloro-9,10-dimethyl-8H-thieno[2',3':4,5]pyrimido[2,1-a]phthalazin-8-one (CAS 315676-39-2), molecular formula C15H10ClN3OS and molecular weight 315.78 g/mol, is a CATO reference standard with documented purity and traceability.

5-Chloro-9,10-dimethyl-8H-thieno[2',3':4,5]pyrimido[2,1-a]phthalazin-8-one (C15H10ClN3OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 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.

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.

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.
