6-Amino-4-(6-bromobenzo[d][1,3]dioxol-5-yl)-3-methyl-1,4-dihydropyrano[2,3-c]pyrazole-5-carbonitrile CAS 332177-32-9

Description

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.

CATO supplies 6-Amino-4-(6-bromobenzo[d][1,3]dioxol-5-yl)-3-methyl-1,4-dihydropyrano[2,3-c]pyrazole-5-carbonitrile (CAS 332177-32-9), a certified reference material (molecular formula C15H11BrN4O3, MW 375.18 g/mol) for analytical method development and quality control.

Based on its molecular formula C15H11BrN4O3, 6-Amino-4-(6-bromobenzo[d][1,3]dioxol-5-yl)-3-methyl-1,4-dihydropyrano[2,3-c]pyrazole-5-carbonitrile contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 375.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
