Chemical Structure

Trans-11-octadecenoic acid-1,2,3,9,10-<SUP>13</SUP>C<SUB>5</SUB> CAS 1255644-59-7 chemical structure

Description

The molecular framework of Trans-11-octadecenoic acid-1,2,3,9,10-<SUP>13</SUP>C<SUB>5</SUB> (C13[13C]5H34O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO supplies Trans-11-octadecenoic acid-1,2,3,9,10-<SUP>13</SUP>C<SUB>5</SUB> (CAS 1255644-59-7), a certified reference material (molecular formula C13[13C]5H34O2, MW 287.42 g/mol) for analytical method development and quality control.

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.
