7635-54-3 A838679 [(1S,2R,5S)-5-methyl-2-propan-2-yl-cyclohexyl] carbonochloridate carbonochloridic acid [(1S,2R,5S)-5-methyl-2-propan-2-ylcyclohexyl] ester (CAS 7635-54-3), molecular formula C11H19ClO2 and molecular weight 218.72 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, 7635-54-3 A838679 [(1S,2R,5S)-5-methyl-2-propan-2-yl-cyclohexyl] carbonochloridate carbonochloridic acid [(1S,2R,5S)-5-methyl-2-propan-2-ylcyclohexyl] ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 218.72 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
