6-(3,5-Dimethyl-1H-pyrazol-1-yl)-2-(3-(2,5-dimethyl-1H-pyrrol-1-yl)thiophen-2-yl)-7-(3-nitrophenyl)pyrazolo[1,5-a]pyrimidine CAS 956181-70-7

Description

CATO supplies 6-(3,5-Dimethyl-1H-pyrazol-1-yl)-2-(3-(2,5-dimethyl-1H-pyrrol-1-yl)thiophen-2-yl)-7-(3-nitrophenyl)pyrazolo[1,5-a]pyrimidine (CAS 956181-70-7), a certified reference material (molecular formula C27H23N7O2S, MW 509.58 g/mol) for analytical method development and quality control.

The molecular framework of 6-(3,5-Dimethyl-1H-pyrazol-1-yl)-2-(3-(2,5-dimethyl-1H-pyrrol-1-yl)thiophen-2-yl)-7-(3-nitrophenyl)pyrazolo[1,5-a]pyrimidine (C27H23N7O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 manufactures 6-(3,5-Dimethyl-1H-pyrazol-1-yl)-2-(3-(2,5-dimethyl-1H-pyrrol-1-yl)thiophen-2-yl)-7-(3-nitrophenyl)pyrazolo[1,5-a]pyrimidine under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation.
