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 2,5-Dimethyl-6-[(2E)-3-phenylprop-2-en-1-yl]pyrazolo[1,5-a]pyrimidin-7-ol.
2,5-Dimethyl-6-[(2E)-3-phenylprop-2-en-1-yl]pyrazolo[1,5-a]pyrimidin-7-ol (CAS 865657-99-4) is a high-purity analytical reference standard with the molecular formula C17H17N3O and a molecular weight of 279.34 g/mol.
The molecular framework of 2,5-Dimethyl-6-[(2E)-3-phenylprop-2-en-1-yl]pyrazolo[1,5-a]pyrimidin-7-ol (C17H17N3O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
