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 Tiludronate disodium hemihydrate.
Tiludronate disodium hemihydrate (CAS 155453-10-4), molecular formula C7H7ClO6P2SNaH2O and molecular weight 357.59 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a salt form, a carbohydrate-derived structure, a sulfone group, a phosphate ester group, chlorine substitution, Tiludronate disodium hemihydrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 357.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Tiludronate disodium hemihydrate 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.
