CATO supplies 3-((trimethylsilyl)ethynyl)benzaldehyde 3-(Trimethylsilyl)ethynylbenzaldehyde 77123-55-8 (CAS 77123-55-8), a certified reference material (molecular formula C12H20OSi, MW 208.37 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, 3-((trimethylsilyl)ethynyl)benzaldehyde 3-(Trimethylsilyl)ethynylbenzaldehyde 77123-55-8 is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 208.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures 3-((trimethylsilyl)ethynyl)benzaldehyde 3-(Trimethylsilyl)ethynylbenzaldehyde 77123-55-8 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
