1-[4-Amino-7-(3-tert-butyldimethylsilyloxypropyl)-5-(4-methylphenyl)-7H-pyrrolo[2,3-d]pyrimidine CAS 821794-84-7

Description

The occurrence of 1-[4-Amino-7-(3-tert-butyldimethylsilyloxypropyl)-5-(4-methylphenyl)-7H-pyrrolo[2,3-d]pyrimidine is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-[4-Amino-7-(3-tert-butyldimethylsilyloxypropyl)-5-(4-methylphenyl)-7H-pyrrolo[2,3-d]pyrimidine (CAS 821794-84-7), molecular formula C22H32N4OSi and molecular weight 396.60 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 1-[4-Amino-7-(3-tert-butyldimethylsilyloxypropyl)-5-(4-methylphenyl)-7H-pyrrolo[2,3-d]pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 396.60 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
