5-Ethynyl-7H-pyrrolo[2,3-d]pyrimidine CAS 905581-05-7

Description

The occurrence of 5-Ethynyl-7H-pyrrolo[2,3-d]pyrimidine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Ethynyl-7H-pyrrolo[2,3-d]pyrimidine (CAS 905581-05-7) is a high-purity analytical reference standard with the molecular formula C8H5N3 and a molecular weight of 143.15 g/mol.

The molecular framework of 5-Ethynyl-7H-pyrrolo[2,3-d]pyrimidine (C8H5N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
