Chemical Structure
Description
The occurrence of 3-Chloro-3-methylbutanoic Acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Chloro-3-methylbutanoic Acid (CAS 60786-20-1) is a high-purity analytical reference standard with the molecular formula C5H9ClO2 and a molecular weight of 136.58 g/mol.
3-Chloro-3-methylbutanoic Acid (C5H9ClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
