Compared with other compounds in its class, the molecular weight of 314.88 g/mol gives Methyl (R)-2-[(tert-Butyldimethylsilyl)oxy]-2-(3-chlorophenyl)acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Methyl (R)-2-[(tert-Butyldimethylsilyl)oxy]-2-(3-chlorophenyl)acetate (CAS 153294-01-0), a certified reference material (molecular formula C15H23ClO3Si, MW 314.88 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Methyl (R)-2-[(tert-Butyldimethylsilyl)oxy]-2-(3-chlorophenyl)acetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 314.88 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
