Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1H-Pyrrolo[2,3-b]pyridin-5-amine, 4-chloro-.
1H-Pyrrolo[2,3-b]pyridin-5-amine, 4-chloro- (CAS 930293-37-1) is a high-purity analytical reference standard with the molecular formula C7H6ClN3 and a molecular weight of 167.60 g/mol.
Structurally, 1H-Pyrrolo[2,3-b]pyridin-5-amine, 4-chloro- (C7H6ClN3) contains a nitrile group, chlorine substitution, 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 167.60 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
