Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including tert-Butyl 2,2-difluoro-3-(methacryloyloxy)pentanoate.
tert-Butyl 2,2-difluoro-3-(methacryloyloxy)pentanoate (CAS 1092693-73-6), molecular formula C13H20F2O4 and molecular weight 278.29 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, tert-Butyl 2,2-difluoro-3-(methacryloyloxy)pentanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 278.29 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.
