Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3S,6R,7S,8S,12Z,15S,16E)-3,7,15-Tris-{[tert-butyl(dimethyl)silyl]oxy}-4,4,6,8,12,16-hexamethyl-17-(2-methyl-1,3-thiazol-4-yl)-5-oxo-heptadeca-12,16-dienoic Acid.

CATO supplies (3S,6R,7S,8S,12Z,15S,16E)-3,7,15-Tris-{[tert-butyl(dimethyl)silyl]oxy}-4,4,6,8,12,16-hexamethyl-17-(2-methyl-1,3-thiazol-4-yl)-5-oxo-heptadeca-12,16-dienoic Acid (CAS 193146-63-3), a certified reference material (molecular formula C45H85NO6SSi3, MW 852.48 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (3S,6R,7S,8S,12Z,15S,16E)-3,7,15-Tris-{[tert-butyl(dimethyl)silyl]oxy}-4,4,6,8,12,16-hexamethyl-17-(2-methyl-1,3-thiazol-4-yl)-5-oxo-heptadeca-12,16-dienoic Acid is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 852.48 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.

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.
