(S)-4-((3,6-dibromo-9H-carbazol-9-yl)methyl)-2-methyl-4,5-dihydrooxazole CAS 2357079-96-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-4-((3,6-dibromo-9H-carbazol-9-yl)methyl)-2-methyl-4,5-dihydrooxazole.

(S)-4-((3,6-dibromo-9H-carbazol-9-yl)methyl)-2-methyl-4,5-dihydrooxazole (CAS 2357079-96-8), molecular formula C17H14Br2N2O and molecular weight 422.11 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, bromine substitution, (S)-4-((3,6-dibromo-9H-carbazol-9-yl)methyl)-2-methyl-4,5-dihydrooxazole is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 422.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
