Description

CATO supplies (2E)-3-[1-[(1alpha,3beta,5Z,7E,22E,24R)-1,3,24-Trihydroxy-9,10-secochola-5,7,10(19),22-tetraen-24-yl]cyclopropyl]-2-propenoic Acid Ethyl Ester (CAS 186371-96-0), a certified reference material (molecular formula C32H46O5, MW 510.70 g/mol) for analytical method development and quality control.

Based on its molecular formula C32H46O5, (2E)-3-[1-[(1alpha,3beta,5Z,7E,22E,24R)-1,3,24-Trihydroxy-9,10-secochola-5,7,10(19),22-tetraen-24-yl]cyclopropyl]-2-propenoic Acid Ethyl Ester contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 510.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), (2E)-3-[1-[(1alpha,3beta,5Z,7E,22E,24R)-1,3,24-Trihydroxy-9,10-secochola-5,7,10(19),22-tetraen-24-yl]cyclopropyl]-2-propenoic Acid Ethyl Ester 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.
