Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 314.46 g/mol gives Methyl Retinoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Methyl Retinoate (CAS 339-16-2), a certified reference material (molecular formula C21H30O2, MW 314.46 g/mol) for analytical method development and quality control.
Structurally, Methyl Retinoate (C21H30O2) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 314.46 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
