Description
CATO supplies 1310250-38-4 3-Bromo-9-chloro-5,6,7,8-tetrahydro-pyrazolo[5,1-b]quinazoline 3628AD C10H9BrClN3 (CAS 1310250-38-4), a certified reference material (molecular formula C10H9BrClN3, MW 286.56 g/mol) for analytical method development and quality control.
Structurally, 1310250-38-4 3-Bromo-9-chloro-5,6,7,8-tetrahydro-pyrazolo[5,1-b]quinazoline 3628AD C10H9BrClN3 (C10H9BrClN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 286.56 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.
