Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2555-30-8 L0487H6Q0H 7-Hydroxy-4-phenylcoumarin UNII-L0487H6Q0H 2H-1-Benzopyran-2-one, 7-hydroxy-4-phenyl- 4-Phenyl-7-hydroxycoumarin 4-Phenylumbelliferone NSC-78474.

CATO supplies 2555-30-8 L0487H6Q0H 7-Hydroxy-4-phenylcoumarin UNII-L0487H6Q0H 2H-1-Benzopyran-2-one, 7-hydroxy-4-phenyl- 4-Phenyl-7-hydroxycoumarin 4-Phenylumbelliferone NSC-78474 (CAS 2555-30-8), a certified reference material (molecular formula C15H22O3, MW 250.33 g/mol) for analytical method development and quality control.

Based on its molecular formula C15H22O3, 2555-30-8 L0487H6Q0H 7-Hydroxy-4-phenylcoumarin UNII-L0487H6Q0H 2H-1-Benzopyran-2-one, 7-hydroxy-4-phenyl- 4-Phenyl-7-hydroxycoumarin 4-Phenylumbelliferone NSC-78474 contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 250.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 2555-30-8 L0487H6Q0H 7-Hydroxy-4-phenylcoumarin UNII-L0487H6Q0H 2H-1-Benzopyran-2-one, 7-hydroxy-4-phenyl- 4-Phenyl-7-hydroxycoumarin 4-Phenylumbelliferone NSC-78474 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.
