Description

Compared with other compounds in its class, the molecular weight of 350.27 g/mol gives 7-Chloro-N-(2-((4-chlorophenyl)thio)ethyl)quinazolin-4-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

7-Chloro-N-(2-((4-chlorophenyl)thio)ethyl)quinazolin-4-amine (CAS 477862-06-9), molecular formula C16H13Cl2N3S and molecular weight 350.27 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 7-Chloro-N-(2-((4-chlorophenyl)thio)ethyl)quinazolin-4-amine (C16H13Cl2N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 350.27 g/mol, it falls into the moderately-high-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.

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), 7-Chloro-N-(2-((4-chlorophenyl)thio)ethyl)quinazolin-4-amine 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.
