Description

Compared with other compounds in its class, the molecular weight of 215.27 g/mol gives 3-Amino-5-(2-benzothienyl)pyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Amino-5-(2-benzothienyl)pyrazole (CAS 1323441-05-9), molecular formula C11H9N3S and molecular weight 215.27 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-Amino-5-(2-benzothienyl)pyrazole (C11H9N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 215.27 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.
