Chemical Structure
Description
The occurrence of 2,4-dichloro-6-iodo-7-methyl-7H-pyrrolo[2,3-d]pyrimidine is closely related to a nitrile group, chlorine/iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,4-dichloro-6-iodo-7-methyl-7H-pyrrolo[2,3-d]pyrimidine (CAS 1638763-42-4), molecular formula C7H12Cl2IN3 and molecular weight 336.00 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,4-dichloro-6-iodo-7-methyl-7H-pyrrolo[2,3-d]pyrimidine (C7H12Cl2IN3) contains a nitrile group, chlorine/iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 336.00 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
