Chemical Structure
Description
2-Keto-(3-methyl-<SUP>13</SUP>C)-butyric-4-<SUP>13</SUP>C,3-d<SUB> </SUB>acid sodium salt (CAS 1216972-87-0), molecular formula C3[13C]2H6DO3 Na and molecular weight 127.09 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Keto-(3-methyl-<SUP>13</SUP>C)-butyric-4-<SUP>13</SUP>C,3-d<SUB> </SUB>acid sodium salt (C3[13C]2H6DO3 Na) is characterized by deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage. 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), 2-Keto-(3-methyl-<SUP>13</SUP>C)-butyric-4-<SUP>13</SUP>C,3-d<SUB> </SUB>acid sodium salt 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.
