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.
QR98QIO1QL 2917-26-2 Hexadecanethiol 1-Hexadecanethiol Cetyl mercaptan EINECS 220-846-6 n-Hexadecanethiol Hexadecyl mercaptan n-Hexadecyl mercaptan NSC 57866 UNII-QR98QIO1QL Cetylmercaptan (CAS 2917-26-2), molecular formula C16H34S and molecular weight 258.51 g/mol, is a CATO reference standard with documented purity and traceability.
QR98QIO1QL 2917-26-2 Hexadecanethiol 1-Hexadecanethiol Cetyl mercaptan EINECS 220-846-6 n-Hexadecanethiol Hexadecyl mercaptan n-Hexadecyl mercaptan NSC 57866 UNII-QR98QIO1QL Cetylmercaptan (C16H34S) contains sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
