Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2-{6-chloro-5,7-dimethylpyrazolo[1,5-a]pyrimidin-2-yl}thiophen-3-yl)-2,5-dimethyl-1H-pyrrole.
1-(2-{6-chloro-5,7-dimethylpyrazolo[1,5-a]pyrimidin-2-yl}thiophen-3-yl)-2,5-dimethyl-1H-pyrrole (CAS 439110-96-0) is a high-purity analytical reference standard with the molecular formula C18H17ClN4S and a molecular weight of 356.87 g/mol.
The molecular framework of 1-(2-{6-chloro-5,7-dimethylpyrazolo[1,5-a]pyrimidin-2-yl}thiophen-3-yl)-2,5-dimethyl-1H-pyrrole (C18H17ClN4S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. 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. 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 1-(2-{6-chloro-5,7-dimethylpyrazolo[1,5-a]pyrimidin-2-yl}thiophen-3-yl)-2,5-dimethyl-1H-pyrrole 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.
