4269-77-6 4,5-Dihydrotestolactone D-Homo-17a-oxaandrost-1-ene-3,17-dione, (5beta)- 13-Hydroxy-3-oxo-13,17-secoandrost-1-en-17-oic acid delta-lactone CAS 4269-77-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4269-77-6 4,5-Dihydrotestolactone D-Homo-17a-oxaandrost-1-ene-3,17-dione, (5beta)- 13-Hydroxy-3-oxo-13,17-secoandrost-1-en-17-oic acid delta-lactone.

CATO supplies 4269-77-6 4,5-Dihydrotestolactone D-Homo-17a-oxaandrost-1-ene-3,17-dione, (5beta)- 13-Hydroxy-3-oxo-13,17-secoandrost-1-en-17-oic acid delta-lactone (CAS 4269-77-6), a certified reference material (molecular formula C19H26O3, MW 302.41 g/mol) for analytical method development and quality control.

Based on its molecular formula C19H26O3, 4269-77-6 4,5-Dihydrotestolactone D-Homo-17a-oxaandrost-1-ene-3,17-dione, (5beta)- 13-Hydroxy-3-oxo-13,17-secoandrost-1-en-17-oic acid delta-lactone contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 302.41 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
