(2E)-2-(3-Methylbutylidene)-2,3,4,9-tetrahydro-1H-carbazol-1-one CAS 866149-06-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (2E)-2-(3-Methylbutylidene)-2,3,4,9-tetrahydro-1H-carbazol-1-one.

(2E)-2-(3-Methylbutylidene)-2,3,4,9-tetrahydro-1H-carbazol-1-one (CAS 866149-06-6) is a high-purity analytical reference standard with the molecular formula C17H19NO and a molecular weight of 253.34 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (2E)-2-(3-Methylbutylidene)-2,3,4,9-tetrahydro-1H-carbazol-1-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 253.34 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.

As a certified reference material (CRM), (2E)-2-(3-Methylbutylidene)-2,3,4,9-tetrahydro-1H-carbazol-1-one 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.
