Chemical Structure
Description
Dodecanedioic acid, polymer with 1,6-hexanediamine and hexanedioic acid (CAS 25267-85-0) is a high-purity analytical reference standard with the molecular formula C12H22O4C6H10O4C6H16N2 and a molecular weight of 492.65 g/mol.
Dodecanedioic acid, polymer with 1,6-hexanediamine and hexanedioic acid (C12H22O4C6H10O4C6H16N2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
