Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 329.65 g/mol gives Hydroxymethylclenbuterol Hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Hydroxymethylclenbuterol Hydrochloride (CAS 37162-89-3) is a high-purity analytical reference standard with the molecular formula C12H18Cl2N2O2HCl and a molecular weight of 329.65 g/mol.
The molecular framework of Hydroxymethylclenbuterol Hydrochloride (C12H18Cl2N2O2HCl) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
