Chemical Structure

Spiro-TTB CAS 515834-67-0 chemical structure

Description

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.

Spiro-TTB (CAS 515834-67-0), molecular formula C81H68N4 and molecular weight 1097.43 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Spiro-TTB (C81H68N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 50.0, corresponding to approximately 50 ring(s) or double-bond equivalent(s). With a molecular weight of 1097.43 g/mol, it falls into the high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
