Chemical Structure
Description
The occurrence of 4-(Tributylstannyl)aniline is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-(Tributylstannyl)aniline (CAS 191980-51-5), molecular formula C18H33NSn and molecular weight 382.17 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 4-(Tributylstannyl)aniline (C18H33NSn) contains a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 382.17 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-(Tributylstannyl)aniline 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.
