Chemical Structure
Description
1398AF 5,7-Dimethyl-pyrazolo[1,5-a]pyrimidine-3-carbaldehyde 878414-63-2 C9H9N3O (CAS 878414-63-2) is a high-purity analytical reference standard with the molecular formula C9H17N3O and a molecular weight of 183.25 g/mol.
Owing to an amide group, a hydroxyl group, an ether linkage, 1398AF 5,7-Dimethyl-pyrazolo[1,5-a]pyrimidine-3-carbaldehyde 878414-63-2 C9H9N3O is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 183.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
