Chemical Structure

CAY10503 CAS 890854-82-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 278.30 g/mol gives CAY10503 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CAY10503 (CAS 890854-82-7), molecular formula C18H14O3 and molecular weight 278.30 g/mol, is a CATO reference standard with documented purity and traceability.

CAY10503 (C18H14O3) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
