Chemical Structure
Description
Structurally, 3-(4,5-Dichloropyrimidin-2-yl)pyrazolo[1,5-a]pyridine (C11H6Cl2N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 265.10 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
3-(4,5-Dichloropyrimidin-2-yl)pyrazolo[1,5-a]pyridine (CAS 1331768-91-2) is a high-purity analytical reference standard with the molecular formula C11H6Cl2N4 and a molecular weight of 265.10 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
