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.
78140-47-3 2,2,6,6-Tetramethyl-4-[(triphenyl-lambda~5~-phosphanylidene)amino]piperidin-1-ol DTXSID80676262 (CAS 78140-47-3), molecular formula C27H32N2OP and molecular weight 431.53 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, 78140-47-3 2,2,6,6-Tetramethyl-4-[(triphenyl-lambda~5~-phosphanylidene)amino]piperidin-1-ol DTXSID80676262 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 431.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
