Chemical Structure

1-Ethynyl-2-isopropoxybenzene CAS 66021-95-2 chemical structure

Description

1-Ethynyl-2-isopropoxybenzene (CAS 66021-95-2), molecular formula C11H12O and molecular weight 160.21 g/mol, is a CATO reference standard with documented purity and traceability.

1-Ethynyl-2-isopropoxybenzene (C11H12O) contains a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
