Chemical Structure

5'-Chloro-6-methoxy-1',3',3'-trimethyl-1',3'-dihydrospiro[chromene-2,2'-indole] CAS 209059-33-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 341.83 g/mol gives 5'-Chloro-6-methoxy-1',3',3'-trimethyl-1',3'-dihydrospiro[chromene-2,2'-indole] distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5'-Chloro-6-methoxy-1',3',3'-trimethyl-1',3'-dihydrospiro[chromene-2,2'-indole] (CAS 209059-33-6), molecular formula C20H20ClNO2 and molecular weight 341.83 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 5'-Chloro-6-methoxy-1',3',3'-trimethyl-1',3'-dihydrospiro[chromene-2,2'-indole] (C20H20ClNO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 341.83 g/mol, it falls into the moderately-high-molecular-weight range. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 5'-Chloro-6-methoxy-1',3',3'-trimethyl-1',3'-dihydrospiro[chromene-2,2'-indole] meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
