8-Hydrazinyl-3-phenylcyclohepta[b]pyrrole CAS 63725-20-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 8-Hydrazinyl-3-phenylcyclohepta[b]pyrrole.

8-Hydrazinyl-3-phenylcyclohepta[b]pyrrole (CAS 63725-20-2), molecular formula C15H13N3 and molecular weight 235.28 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 8-Hydrazinyl-3-phenylcyclohepta[b]pyrrole (C15H13N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 235.28 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
