Chemical Structure
Description
173458-82-7 7H-Pyrrolo[2,3-d]pyrimidine, 4-chloro-5,6-diphenyl-7-(phenylmethyl)- CTK0A7674 (CAS 173458-82-7) is a high-purity analytical reference standard with the molecular formula C25H18ClN3 and a molecular weight of 395.88 g/mol.
Structurally, 173458-82-7 7H-Pyrrolo[2,3-d]pyrimidine, 4-chloro-5,6-diphenyl-7-(phenylmethyl)- CTK0A7674 (C25H18ClN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 395.88 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.
