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 Poly(oxy-1,2-ethanediyl), .alpha.-sulfo-.omega.-(tetradecyloxy)-, ammonium salt (1:1).
CATO supplies Poly(oxy-1,2-ethanediyl), .alpha.-sulfo-.omega.-(tetradecyloxy)-, ammonium salt (1:1) (CAS 27731-61-9), a certified reference material (molecular formula C28H58OO4SH4N, MW 524.87 g/mol) for analytical method development and quality control.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Poly(oxy-1,2-ethanediyl), .alpha.-sulfo-.omega.-(tetradecyloxy)-, ammonium salt (1:1) is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 524.87 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
