Chemical Structure

Rauwolscine CAS 131-03-3 chemical structure

Description

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.

CATO supplies Rauwolscine (CAS 131-03-3), a certified reference material (molecular formula C21H26N2O3, MW 354.44 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Rauwolscine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 354.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), Rauwolscine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
