Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Phenylbutazone-(diphenyl-<SUP>13</SUP>C<SUB>12</SUB>).
Phenylbutazone-(diphenyl-<SUP>13</SUP>C<SUB>12</SUB>) (CAS 1325559-13-4), molecular formula C7[13C]12H20N2O2 and molecular weight 320.29 g/mol, is a CATO reference standard with documented purity and traceability.
Phenylbutazone-(diphenyl-<SUP>13</SUP>C<SUB>12</SUB>) (C7[13C]12H20N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
