(3r)-2-Acetyl-1-phenyl-1h,2h,3h,4h,9h-pyrido[3,4-b]indole-3-carboxylic acid CAS 956923-54-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 334.37 g/mol gives (3r)-2-Acetyl-1-phenyl-1h,2h,3h,4h,9h-pyrido[3,4-b]indole-3-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(3r)-2-Acetyl-1-phenyl-1h,2h,3h,4h,9h-pyrido[3,4-b]indole-3-carboxylic acid (CAS 956923-54-9), molecular formula C20H18N2O3 and molecular weight 334.37 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, (3r)-2-Acetyl-1-phenyl-1h,2h,3h,4h,9h-pyrido[3,4-b]indole-3-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 334.37 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.

CATO manufactures (3r)-2-Acetyl-1-phenyl-1h,2h,3h,4h,9h-pyrido[3,4-b]indole-3-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.
