7-(tert-Butyl)-4-chloro-7H-pyrrolo[2,3-d]pyrimidine CAS 1402444-77-2

Description

The occurrence of 7-(tert-Butyl)-4-chloro-7H-pyrrolo[2,3-d]pyrimidine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 7-(tert-Butyl)-4-chloro-7H-pyrrolo[2,3-d]pyrimidine (CAS 1402444-77-2), a certified reference material (molecular formula C10H12ClN3, MW 209.68 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 7-(tert-Butyl)-4-chloro-7H-pyrrolo[2,3-d]pyrimidine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 209.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
