Chemical Structure

CH2COOH-PEG9-CH2COOH CAS 2250056-46-1 chemical structure

Description

The occurrence of CH2COOH-PEG9-CH2COOH is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CH2COOH-PEG9-CH2COOH (CAS 2250056-46-1), molecular formula C22H42O14 and molecular weight 530.56 g/mol, is a CATO reference standard with documented purity and traceability.

CH2COOH-PEG9-CH2COOH (C22H42O14) 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.

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.
