Description

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.

71YMM1X75O 70142-34-6 Polyoxyl 15 hydroxystearate [NF] Octadecanoic acid, 12-hydroxy-, polymer with alpha-hydro-omega-hydroxypoly(oxy-1,2-ethanediyl) Polyoxyl 15 hydroxystearate UNII-71YMM1X75O 12-Hydroxystearic acid-polyethylene glycol copolymer, minimum number average molecular weight (in amu), 3,690 (CAS 70142-34-6), molecular formula C47H94O19 and molecular weight 963.24 g/mol, is a CATO reference standard with documented purity and traceability.

71YMM1X75O 70142-34-6 Polyoxyl 15 hydroxystearate [NF] Octadecanoic acid, 12-hydroxy-, polymer with alpha-hydro-omega-hydroxypoly(oxy-1,2-ethanediyl) Polyoxyl 15 hydroxystearate UNII-71YMM1X75O 12-Hydroxystearic acid-polyethylene glycol copolymer, minimum number average molecular weight (in amu), 3,690 (C47H94O19) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
