4-((Trimethylsilyl)ethynyl)picolinaldehyde CAS 1196151-87-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

4-((Trimethylsilyl)ethynyl)picolinaldehyde (CAS 1196151-87-7), molecular formula C11H13NOSi and molecular weight 203.31 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 4-((Trimethylsilyl)ethynyl)picolinaldehyde (C11H13NOSi) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
