Chemical Structure

2-(Hydroxymethyl)-3,6,7,8-tetrahydro-4H-cyclopenta[g]quinazolin-4-one CAS 501131-95-9 chemical structure

Description

The occurrence of 2-(Hydroxymethyl)-3,6,7,8-tetrahydro-4H-cyclopenta[g]quinazolin-4-one is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-(Hydroxymethyl)-3,6,7,8-tetrahydro-4H-cyclopenta[g]quinazolin-4-one (CAS 501131-95-9), a certified reference material (molecular formula C12H12N2O2, MW 216.24 g/mol) for analytical method development and quality control.

2-(Hydroxymethyl)-3,6,7,8-tetrahydro-4H-cyclopenta[g]quinazolin-4-one (C12H12N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), 2-(Hydroxymethyl)-3,6,7,8-tetrahydro-4H-cyclopenta[g]quinazolin-4-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.
