2-{3a-methyl-1,5-dioxo-1h,2h,3h,3ah,4h,5h-pyrrolo[1,2-a]quinazolin-4-yl}acetic acid CAS 1000933-03-8

Description

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.

2-{3a-methyl-1,5-dioxo-1h,2h,3h,3ah,4h,5h-pyrrolo[1,2-a]quinazolin-4-yl}acetic acid (CAS 1000933-03-8), molecular formula C14H14N2O4 and molecular weight 274.27 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2-{3a-methyl-1,5-dioxo-1h,2h,3h,3ah,4h,5h-pyrrolo[1,2-a]quinazolin-4-yl}acetic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 274.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
