Chemical Structure

1,1'-(Pentane-3,3-diyl)bis(1H-pyrazole) CAS 28791-86-8 chemical structure

Description

As a certified reference material (CRM), 1,1'-(Pentane-3,3-diyl)bis(1H-pyrazole) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

1,1'-(Pentane-3,3-diyl)bis(1H-pyrazole) (CAS 28791-86-8) is a high-purity analytical reference standard with the molecular formula C11H16N4 and a molecular weight of 204.27 g/mol.

Based on its molecular formula C11H16N4, 1,1'-(Pentane-3,3-diyl)bis(1H-pyrazole) contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 204.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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