3-Methoxy-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one CAS 111375-28-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Methoxy-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one.

CATO supplies 3-Methoxy-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one (CAS 111375-28-1), a certified reference material (molecular formula C6H6N4O2, MW 166.14 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 3-Methoxy-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 166.14 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), 3-Methoxy-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one 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.
