Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
CATO supplies 688-73-3 4XDX163P3D Tributyltin Tri-n-butyltin hydride Stannane, tributyl- Stannane, tri-n-butyl-, hydride Tributylstannane 4-04-00-04312 (Beilstein Handbook Reference) BRN 3587329 EINECS 211-704-4 HSDB 6362 Tin, tri-n-butyl-, hydride Tri-n-butylstannane hydride Tributylstannic hydride Tributyltin hydride Tributlytin UNII-4XDX163P3D (CAS 688-73-3), a certified reference material (molecular formula C12H28Sn, MW 291.06 g/mol) for analytical method development and quality control.
The molecular framework of 688-73-3 4XDX163P3D Tributyltin Tri-n-butyltin hydride Stannane, tributyl- Stannane, tri-n-butyl-, hydride Tributylstannane 4-04-00-04312 (Beilstein Handbook Reference) BRN 3587329 EINECS 211-704-4 HSDB 6362 Tin, tri-n-butyl-, hydride Tri-n-butylstannane hydride Tributylstannic hydride Tributyltin hydride Tributlytin UNII-4XDX163P3D (C12H28Sn) is characterized by an organic framework. 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. 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.
