Description

The occurrence of 5-(1-(5-((5-((2H-Pyrrol-2-ylidene)methyl)-2H-pyrrol-2-ylidene)methyl)-3-methyl-2H-pyrrol-2-ylidene)ethyl)-4-methyl-3-((trimethylsilyl)oxy)-1H-pyrrol-2-yl nicotinate is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-(1-(5-((5-((2H-Pyrrol-2-ylidene)methyl)-2H-pyrrol-2-ylidene)methyl)-3-methyl-2H-pyrrol-2-ylidene)ethyl)-4-methyl-3-((trimethylsilyl)oxy)-1H-pyrrol-2-yl nicotinate (CAS 183274-22-8), molecular formula C12H21NO3Si2 and molecular weight 283.47 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5-(1-(5-((5-((2H-Pyrrol-2-ylidene)methyl)-2H-pyrrol-2-ylidene)methyl)-3-methyl-2H-pyrrol-2-ylidene)ethyl)-4-methyl-3-((trimethylsilyl)oxy)-1H-pyrrol-2-yl nicotinate (C12H21NO3Si2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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 283.47 g/mol, it falls into the medium-molecular-weight range. 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), 5-(1-(5-((5-((2H-Pyrrol-2-ylidene)methyl)-2H-pyrrol-2-ylidene)methyl)-3-methyl-2H-pyrrol-2-ylidene)ethyl)-4-methyl-3-((trimethylsilyl)oxy)-1H-pyrrol-2-yl nicotinate 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.
