6-Amino-4-[4-(cyclopentyloxy)-3-methoxyphenyl]-3-(2,4-dimethylphenyl)-2H,4H-pyrano[2,3-c]pyrazole-5-carbonitrile CAS 903086-86-2

Description

6-Amino-4-[4-(cyclopentyloxy)-3-methoxyphenyl]-3-(2,4-dimethylphenyl)-2H,4H-pyrano[2,3-c]pyrazole-5-carbonitrile (CAS 903086-86-2), molecular formula C27H28N4O3 and molecular weight 456.54 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 6-Amino-4-[4-(cyclopentyloxy)-3-methoxyphenyl]-3-(2,4-dimethylphenyl)-2H,4H-pyrano[2,3-c]pyrazole-5-carbonitrile (C27H28N4O3) is characterized by a steroid core, an amide 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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-Amino-4-[4-(cyclopentyloxy)-3-methoxyphenyl]-3-(2,4-dimethylphenyl)-2H,4H-pyrano[2,3-c]pyrazole-5-carbonitrile under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
