RH-34 CAS 1028307-48-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 325.36 g/mol gives RH-34 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies RH-34 (CAS 1028307-48-3), a certified reference material (molecular formula C18H19N3O3, MW 325.36 g/mol) for analytical method development and quality control.

RH-34 (C18H19N3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
