4-(2,6,6-Trimethyl-4-oxo-4,5,6,7-tetrahydro-1H-indol-1-yl)benzoic acid CAS 627835-19-2

Description

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.

CATO supplies 4-(2,6,6-Trimethyl-4-oxo-4,5,6,7-tetrahydro-1H-indol-1-yl)benzoic acid (CAS 627835-19-2), a certified reference material (molecular formula C18H19NO3, MW 297.35 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 4-(2,6,6-Trimethyl-4-oxo-4,5,6,7-tetrahydro-1H-indol-1-yl)benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 297.35 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).

As a certified reference material (CRM), 4-(2,6,6-Trimethyl-4-oxo-4,5,6,7-tetrahydro-1H-indol-1-yl)benzoic acid 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.
