Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Meta-hydroxycinnamic acid-1,2,3-<SUP>13</SUP>C<SUB>3</SUB>.
Meta-hydroxycinnamic acid-1,2,3-<SUP>13</SUP>C<SUB>3</SUB> (CAS 1261170-79-9) is a high-purity analytical reference standard with the molecular formula C6[13C]3H8O3 and a molecular weight of 167.14 g/mol.
Meta-hydroxycinnamic acid-1,2,3-<SUP>13</SUP>C<SUB>3</SUB> (C6[13C]3H8O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
