CATO supplies (20S)-3|A-Acetoxypregn-5-ene-20-carboxaldehyde (3|A,20S)-20-Formyl-3-hydroxy-5-pregnene 3-O-AcetateDiscontinued (3|A,20S)-3-(Acetyloxy)pregn-5-ene-20-carboxaldehyde 10211-88-8 3|A-Acetoxy-22,23-dinorchol-5-en-24-al 3|A-Acetoxybisnor-5-cholen-22-al (CAS 10211-88-8), a certified reference material (molecular formula C24H36O3, MW 372.54 g/mol) for analytical method development and quality control.

Owing to a steroid core, a hydroxyl group, an ether linkage, (20S)-3|A-Acetoxypregn-5-ene-20-carboxaldehyde (3|A,20S)-20-Formyl-3-hydroxy-5-pregnene 3-O-AcetateDiscontinued (3|A,20S)-3-(Acetyloxy)pregn-5-ene-20-carboxaldehyde 10211-88-8 3|A-Acetoxy-22,23-dinorchol-5-en-24-al 3|A-Acetoxybisnor-5-cholen-22-al is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 372.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), (20S)-3|A-Acetoxypregn-5-ene-20-carboxaldehyde (3|A,20S)-20-Formyl-3-hydroxy-5-pregnene 3-O-AcetateDiscontinued (3|A,20S)-3-(Acetyloxy)pregn-5-ene-20-carboxaldehyde 10211-88-8 3|A-Acetoxy-22,23-dinorchol-5-en-24-al 3|A-Acetoxybisnor-5-cholen-22-al 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.
