6-(Chloromethyl)-1-methyl-1h,4h,5h-pyrazolo[3,4-d]pyrimidin-4-one CAS 931075-55-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-(Chloromethyl)-1-methyl-1h,4h,5h-pyrazolo[3,4-d]pyrimidin-4-one.

CATO supplies 6-(Chloromethyl)-1-methyl-1h,4h,5h-pyrazolo[3,4-d]pyrimidin-4-one (CAS 931075-55-7), a certified reference material (molecular formula C7H7ClN4O, MW 198.61 g/mol) for analytical method development and quality control.

Structurally, 6-(Chloromethyl)-1-methyl-1h,4h,5h-pyrazolo[3,4-d]pyrimidin-4-one (C7H7ClN4O) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. 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 198.61 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
