Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Methyl 3-chloro-2-methyl-3-oxopropanoate (CAS 23185-24-2), molecular formula C5H7ClO3 and molecular weight 150.56 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl 3-chloro-2-methyl-3-oxopropanoate (C5H7ClO3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), Methyl 3-chloro-2-methyl-3-oxopropanoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
