4H-Pyrazolo[3,4-d]pyrimidin-4-one, 1,5-dihydro-3-[3-(2-propyn-1-ylsulfinyl)-1-propyn-1-yl]- CAS 2440565-44-4 chemical structure

Description

The occurrence of 4H-Pyrazolo[3,4-d]pyrimidin-4-one, 1,5-dihydro-3-[3-(2-propyn-1-ylsulfinyl)-1-propyn-1-yl]- is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4H-Pyrazolo[3,4-d]pyrimidin-4-one, 1,5-dihydro-3-[3-(2-propyn-1-ylsulfinyl)-1-propyn-1-yl]- (CAS 2440565-44-4) is a high-purity analytical reference standard with the molecular formula C11H8N4O2S and a molecular weight of 260.27 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 4H-Pyrazolo[3,4-d]pyrimidin-4-one, 1,5-dihydro-3-[3-(2-propyn-1-ylsulfinyl)-1-propyn-1-yl]- is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 260.27 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.

As a certified reference material (CRM), 4H-Pyrazolo[3,4-d]pyrimidin-4-one, 1,5-dihydro-3-[3-(2-propyn-1-ylsulfinyl)-1-propyn-1-yl]- meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
