Chemical Structure
Description
Methyl Hydrogen Malonate (CAS 16695-14-0), molecular formula C4H6O4 and molecular weight 118.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl Hydrogen Malonate (C4H6O4) is characterized by a carbohydrate-derived structure. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Methyl Hydrogen Malonate 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.
