Chemical Structure
Description
2-Methoxyphenyl isocyanate 1-Isocyanato-2-methoxybenzene o-Anisyl isocyanate o-Methoxyphenyl isocyanate 700-87-8 (CAS 700-87-8), molecular formula C8H7NO2 and molecular weight 149.15 g/mol, is a CATO reference standard with documented purity and traceability.
2-Methoxyphenyl isocyanate 1-Isocyanato-2-methoxybenzene o-Anisyl isocyanate o-Methoxyphenyl isocyanate 700-87-8 (C8H7NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; 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.
