4-((4,6-Dimethylpyrimidin-2-yl)carbamoyl)-5-methylisoxazole-3-carboxylic acid CAS 339012-78-1

Description

As a certified reference material (CRM), 4-((4,6-Dimethylpyrimidin-2-yl)carbamoyl)-5-methylisoxazole-3-carboxylic 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.

CATO supplies 4-((4,6-Dimethylpyrimidin-2-yl)carbamoyl)-5-methylisoxazole-3-carboxylic acid (CAS 339012-78-1), a certified reference material (molecular formula C12H12N4O4, MW 276.25 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 4-((4,6-Dimethylpyrimidin-2-yl)carbamoyl)-5-methylisoxazole-3-carboxylic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 276.25 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.
