Nexturastat A CAS 1403783-31-2 chemical structure

Description

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.

Nexturastat A (CAS 1403783-31-2) is a high-purity analytical reference standard with the molecular formula C19H23N3O3 and a molecular weight of 341.40 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Nexturastat A is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 341.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
