Chemical Structure

Poly(oxymethylene), .alpha.-acetyl-.omega.-(acetyloxy)- CAS 25231-38-3 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(oxymethylene), .alpha.-acetyl-.omega.-(acetyloxy)-.

Poly(oxymethylene), .alpha.-acetyl-.omega.-(acetyloxy)- (CAS 25231-38-3), molecular formula C5H8O4 and molecular weight 132.11 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Poly(oxymethylene), .alpha.-acetyl-.omega.-(acetyloxy)- (C5H8O4) contains a carbohydrate-derived structure. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 132.11 g/mol, it falls into the low-molecular-weight range.

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.
