Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 5,7-dichloro-4-hydroxyquinoline-3-carboxylate.
CATO supplies Methyl 5,7-dichloro-4-hydroxyquinoline-3-carboxylate (CAS 1820685-13-9), a certified reference material (molecular formula C11H7Cl2NO3, MW 272.08 g/mol) for analytical method development and quality control.
Structurally, Methyl 5,7-dichloro-4-hydroxyquinoline-3-carboxylate (C11H7Cl2NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 272.08 g/mol, it falls into the medium-molecular-weight range. 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), Methyl 5,7-dichloro-4-hydroxyquinoline-3-carboxylate 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.
