Chemical Structure

Palmitic acid-16-<SUP>13</SUP>C CAS 158045-29-5 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Palmitic acid-16-<SUP>13</SUP>C is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 257.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 Palmitic acid-16-<SUP>13</SUP>C (CAS 158045-29-5), a certified reference material (molecular formula C15[13C]H32O2, MW 257.42 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.
