Trans-9-hexadecenoic acid-1,2,3,7,8-<SUP>13</SUP>C<SUB>5</SUB> CAS 1255644-44-0

Description

The occurrence of Trans-9-hexadecenoic acid-1,2,3,7,8-<SUP>13</SUP>C<SUB>5</SUB> is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Trans-9-hexadecenoic acid-1,2,3,7,8-<SUP>13</SUP>C<SUB>5</SUB> (CAS 1255644-44-0) is a high-purity analytical reference standard with the molecular formula C11[13C]5H30O2 and a molecular weight of 259.37 g/mol.

Trans-9-hexadecenoic acid-1,2,3,7,8-<SUP>13</SUP>C<SUB>5</SUB> (C11[13C]5H30O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
