Chemical Structure

5H-Pyrrolo[3,4-d]pyrimidine CAS 671-23-8 chemical structure

Description

Structurally, 5H-Pyrrolo[3,4-d]pyrimidine (C6H5N3) contains a nitrile group, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 119.12 g/mol, it falls into the low-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

CATO supplies 5H-Pyrrolo[3,4-d]pyrimidine (CAS 671-23-8), a certified reference material (molecular formula C6H5N3, MW 119.12 g/mol) for analytical method development and quality control.

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.
