Description
Compared with other compounds in its class, the molecular weight of 254.75 g/mol gives 76674-55-0 2-(4-tert-Butylphenoxy)-2-methylpropanoyl chloride MFCD11941685 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
76674-55-0 2-(4-tert-Butylphenoxy)-2-methylpropanoyl chloride MFCD11941685 (CAS 76674-55-0), molecular formula C14H19ClO2 and molecular weight 254.75 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 76674-55-0 2-(4-tert-Butylphenoxy)-2-methylpropanoyl chloride MFCD11941685 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 254.75 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
