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 2-(7-Chloro-3-iodo-2-methylpyrazolo[1,5-a]pyrimidin-5-yl)butan-1-ol.
2-(7-Chloro-3-iodo-2-methylpyrazolo[1,5-a]pyrimidin-5-yl)butan-1-ol (CAS 2387601-52-5) is a high-purity analytical reference standard with the molecular formula C11H13ClIN3O and a molecular weight of 365.60 g/mol.
Structurally, 2-(7-Chloro-3-iodo-2-methylpyrazolo[1,5-a]pyrimidin-5-yl)butan-1-ol (C11H13ClIN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/iodine substitution. 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 365.60 g/mol, it falls into the moderately-high-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.
