Chemical Structure

1,2-Cyclopentanediol CAS 4065-92-3 chemical structure

Description

1,2-Cyclopentanediol (CAS 4065-92-3), molecular formula C5H10O2 and molecular weight 102.13 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,2-Cyclopentanediol (C5H10O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. 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 102.13 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.
