Chemical Structure
Description
As a certified reference material (CRM), Trimethyl((4-nitrophenyl)ethynyl)silane 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.
Trimethyl((4-nitrophenyl)ethynyl)silane (CAS 75867-38-8), molecular formula C11H13NO2Si and molecular weight 219.31 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Trimethyl((4-nitrophenyl)ethynyl)silane is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 219.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
