Chemical Structure
Description
2-Chloro-N-(3,3-dimethyl-2-oxobutyl)acetamide (CAS 333389-44-9) is a high-purity analytical reference standard with the molecular formula C8H14ClNO2 and a molecular weight of 191.66 g/mol.
2-Chloro-N-(3,3-dimethyl-2-oxobutyl)acetamide (C8H14ClNO2) contains an amide group, 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.
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.
CATO manufactures 2-Chloro-N-(3,3-dimethyl-2-oxobutyl)acetamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
