Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Montelukast Dihydro Impurity (Sodium Salt).
CATO supplies Montelukast Dihydro Impurity (Sodium Salt) (CAS 142147-98-6), a certified reference material (molecular formula C35H37ClNO3SNa, MW 610.18 g/mol) for analytical method development and quality control.
Owing to a salt form, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, Montelukast Dihydro Impurity (Sodium Salt) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 610.18 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), Montelukast Dihydro Impurity (Sodium Salt) 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.
