OCtadecanoic acid, 2-[[3-[(1-oxooctadecyl)oxy]-2,2-bis[[(1-oxooctadecyl)oxy]methyl]propoxy]methyl]-2-[[(1-oxooctadecyl)oxy]methyl]-1,3-propanediyl ester CAS 70969-57-2 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 OCtadecanoic acid, 2-[[3-[(1-oxooctadecyl)oxy]-2,2-bis[[(1-oxooctadecyl)oxy]methyl]propoxy]methyl]-2-[[(1-oxooctadecyl)oxy]methyl]-1,3-propanediyl ester.

CATO supplies OCtadecanoic acid, 2-[[3-[(1-oxooctadecyl)oxy]-2,2-bis[[(1-oxooctadecyl)oxy]methyl]propoxy]methyl]-2-[[(1-oxooctadecyl)oxy]methyl]-1,3-propanediyl ester (CAS 70969-57-2), a certified reference material (molecular formula C118H226O13, MW 1853.05 g/mol) for analytical method development and quality control.

OCtadecanoic acid, 2-[[3-[(1-oxooctadecyl)oxy]-2,2-bis[[(1-oxooctadecyl)oxy]methyl]propoxy]methyl]-2-[[(1-oxooctadecyl)oxy]methyl]-1,3-propanediyl ester (C118H226O13) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
