Poly(oxy-1,2-ethanediyl), .alpha.-eicosyl-.omega.-hydroxy- CAS 26636-39-5

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.-eicosyl-.omega.-hydroxy-.

Poly(oxy-1,2-ethanediyl), .alpha.-eicosyl-.omega.-hydroxy- (CAS 26636-39-5), molecular formula C22H46O2 and molecular weight 342.60 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Poly(oxy-1,2-ethanediyl), .alpha.-eicosyl-.omega.-hydroxy- (C22H46O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 342.60 g/mol, it falls into the moderately-high-molecular-weight range. 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.

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.
