Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 406.48 g/mol gives Crotonaldehyde, DAIH derivative distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Crotonaldehyde, DAIH derivative (CAS 103480-19-9) is a high-purity analytical reference standard with the molecular formula C27H22N2O2 and a molecular weight of 406.48 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Crotonaldehyde, DAIH derivative is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 406.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), Crotonaldehyde, DAIH derivative 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.
