Chemical Structure

4-Benzyl-2,3,4,5-tetrahydrobenzo[f][1,4]oxazepine-5-carboxylic acid hydrochloride CAS 1290628-94-2 chemical structure

Description

4-Benzyl-2,3,4,5-tetrahydrobenzo[f][1,4]oxazepine-5-carboxylic acid hydrochloride (C17H17NO3HCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

4-Benzyl-2,3,4,5-tetrahydrobenzo[f][1,4]oxazepine-5-carboxylic acid hydrochloride (CAS 1290628-94-2), molecular formula C17H17NO3HCl and molecular weight 319.78 g/mol, is a CATO reference standard with documented purity and traceability.

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.
