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 *Resorcinol Impurity 5(benzene-1,3-disulfonic acid).
*Resorcinol Impurity 5(benzene-1,3-disulfonic acid) (CAS 98-48-6), molecular formula C38H68N4O12 and molecular weight 772.97 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, *Resorcinol Impurity 5(benzene-1,3-disulfonic acid) is typically off-white to pale yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 772.97 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).
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), *Resorcinol Impurity 5(benzene-1,3-disulfonic 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.
