Chemical Structure

4-(tert-Butyl)-2-(tributylstannyl)pyridine CAS 894769-22-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(tert-Butyl)-2-(tributylstannyl)pyridine.

4-(tert-Butyl)-2-(tributylstannyl)pyridine (CAS 894769-22-3), molecular formula C21H39NSn and molecular weight 424.25 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, 4-(tert-Butyl)-2-(tributylstannyl)pyridine is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 424.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), 4-(tert-Butyl)-2-(tributylstannyl)pyridine 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.
