Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Hydroxy-PEG1-acid (CAS 89211-34-7), a certified reference material (molecular formula C5H10O4, MW 134.13 g/mol) for analytical method development and quality control.
Structurally, Hydroxy-PEG1-acid (C5H10O4) contains a carbohydrate-derived structure. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 134.13 g/mol, it falls into the low-molecular-weight range.
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.
