Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,2-Propanediol-1,2-<SUP>13</SUP>C<SUB>2</SUB> (CAS 1173019-59-4), molecular formula C[13C]2H8O2 and molecular weight 78.08 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,2-Propanediol-1,2-<SUP>13</SUP>C<SUB>2</SUB> (C[13C]2H8O2) is characterized by 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.
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.
