Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-chloro-1-[(1,1-dimethylethyl)dimethylsilyl]-1H-Pyrrolo[2,3-b]pyridine.
4-chloro-1-[(1,1-dimethylethyl)dimethylsilyl]-1H-Pyrrolo[2,3-b]pyridine (CAS 937796-62-8) is a high-purity analytical reference standard with the molecular formula C13H19ClN2Si and a molecular weight of 266.84 g/mol.
Structurally, 4-chloro-1-[(1,1-dimethylethyl)dimethylsilyl]-1H-Pyrrolo[2,3-b]pyridine (C13H19ClN2Si) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 266.84 g/mol, it falls into the medium-molecular-weight range. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
