3-tert-butyl-6-chloro-1H-pyrazolo[3,4-d]pyrimidine CAS 2763950-72-5 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 3-tert-butyl-6-chloro-1H-pyrazolo[3,4-d]pyrimidine.

CATO supplies 3-tert-butyl-6-chloro-1H-pyrazolo[3,4-d]pyrimidine (CAS 2763950-72-5), a certified reference material (molecular formula C9H19ClN4, MW 218.73 g/mol) for analytical method development and quality control.

Structurally, 3-tert-butyl-6-chloro-1H-pyrazolo[3,4-d]pyrimidine (C9H19ClN4) contains a nitrile group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 218.73 g/mol, it falls into the medium-molecular-weight range. 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.
