2-(7-Chloro-2-methylpyrazolo[1,5-a]pyrimidin-5-yl)-2-methylpropan-1-ol CAS 2387596-87-2 chemical structure

Description

The occurrence of 2-(7-Chloro-2-methylpyrazolo[1,5-a]pyrimidin-5-yl)-2-methylpropan-1-ol is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(7-Chloro-2-methylpyrazolo[1,5-a]pyrimidin-5-yl)-2-methylpropan-1-ol (CAS 2387596-87-2), molecular formula C11H14ClN3O and molecular weight 239.70 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-(7-Chloro-2-methylpyrazolo[1,5-a]pyrimidin-5-yl)-2-methylpropan-1-ol (C11H14ClN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine 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 239.70 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
