Magnesium Stearate CAS 557-04-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Magnesium Stearate.

Magnesium Stearate (CAS 557-04-0), molecular formula C18H35O2Mg and molecular weight 307.78 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Magnesium Stearate (C18H35O2Mg) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.5, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 307.78 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.

CATO manufactures Magnesium Stearate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
