Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-(Benzylthio)-2-phenylpyrazolo[1,5-a]pyrazine.
CATO supplies 4-(Benzylthio)-2-phenylpyrazolo[1,5-a]pyrazine (CAS 1040658-08-9), a certified reference material (molecular formula C19H15N3S, MW 317.41 g/mol) for analytical method development and quality control.
Structurally, 4-(Benzylthio)-2-phenylpyrazolo[1,5-a]pyrazine (C19H15N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 317.41 g/mol, it falls into the moderately-high-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.
