Description

CATO manufactures (3R,4S,4aS,6aS,9S,11aR,11bS)-4,11b-Dimethyl-3-(((Z)-2-methylbut-2-enoyl)oxy)-8-methylenetetradecahydro-6a,9-methanocyclohepta[a]naphthalene-4-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

(3R,4S,4aS,6aS,9S,11aR,11bS)-4,11b-Dimethyl-3-(((Z)-2-methylbut-2-enoyl)oxy)-8-methylenetetradecahydro-6a,9-methanocyclohepta[a]naphthalene-4-carboxylic acid (CAS 74635-61-3) is a high-purity analytical reference standard with the molecular formula C25H36O4 and a molecular weight of 400.55 g/mol.

Owing to a flavonoid core, a hydroxyl group, an ether linkage, (3R,4S,4aS,6aS,9S,11aR,11bS)-4,11b-Dimethyl-3-(((Z)-2-methylbut-2-enoyl)oxy)-8-methylenetetradecahydro-6a,9-methanocyclohepta[a]naphthalene-4-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 400.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
