Chemical Structure

1-Phenyl-5-(tributylstannyl)-1H-pyrazole CAS 141998-89-2 chemical structure

Description

CATO manufactures 1-Phenyl-5-(tributylstannyl)-1H-pyrazole 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.

1-Phenyl-5-(tributylstannyl)-1H-pyrazole (CAS 141998-89-2) is a high-purity analytical reference standard with the molecular formula C21H34N2Sn and a molecular weight of 433.22 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 1-Phenyl-5-(tributylstannyl)-1H-pyrazole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 433.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
