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 1-(4-Bromophenyl)-4-hydrazinyl-1H-pyrazolo[3,4-d]pyrimidine.
CATO supplies 1-(4-Bromophenyl)-4-hydrazinyl-1H-pyrazolo[3,4-d]pyrimidine (CAS 1416346-40-1), a certified reference material (molecular formula C11H9BrN6, MW 305.13 g/mol) for analytical method development and quality control.
Structurally, 1-(4-Bromophenyl)-4-hydrazinyl-1H-pyrazolo[3,4-d]pyrimidine (C11H9BrN6) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 305.13 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
