Chemical Structure

Clenbuterol Hydrochloride CAS 21898-19-1 chemical structure

Description

Clenbuterol Hydrochloride (CAS 21898-19-1) is a high-purity analytical reference standard with the molecular formula C12H18Cl2N2OHCl and a molecular weight of 313.65 g/mol.

Structurally, Clenbuterol Hydrochloride (C12H18Cl2N2OHCl) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 313.65 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
