Chemical Structure
Description
The molecular framework of 3-Isopropyl-1-methyl-4-(propan-2-ylidene)-1,4,6,7-tetrahydrothiopyrano[4,3-c]pyrazole (C13H20N2S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 3-Isopropyl-1-methyl-4-(propan-2-ylidene)-1,4,6,7-tetrahydrothiopyrano[4,3-c]pyrazole (CAS 1956366-05-4), a certified reference material (molecular formula C13H20N2S, MW 236.38 g/mol) for analytical method development and quality control.
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.
