Chemical Structure

Calcitonin Impurity 6 CAS 3680-13-5 chemical structure

Description

Calcitonin Impurity 6 (CAS 3680-13-5) is a high-purity analytical reference standard with the molecular formula C7H14O3S and a molecular weight of 178.25 g/mol.

Structurally, Calcitonin Impurity 6 (C7H14O3S) contains a sulfone group, 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 178.25 g/mol, it falls into the medium-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.
